+   ECMA Section:       15.4 Array Objects
+
+   Description:        Whenever a property is added whose name is an array

+   is not smaller  than the new length is automatically
+   deleted.  This constraint applies only to the Array
+   object itself, and is unaffected by length or array
+   index properties that may be inherited from its
+   prototype.

+   11.   If this object has a property named by Result(8), go to step 12; but
+   if this object has no property named by Result(8), then go to either
+   step 12 or step 14, depending on the implementation.
+   12.   Call the [[Put]] method of this object with arguments Result(7) and

+   13.   Go to step 15.

+   19.   Increase k by 1.

+
+   Note that the reverse function is intentionally generic; it does not require

+   successfully to a host object is implementation dependent.
+
+   Note:   Array.prototype.reverse allows some flexibility in implementation
+   regarding array indices that have not been populated. This test covers the
+   cases in which unpopulated indices are not deleted, since the JavaScript
+   implementation does not delete uninitialzed indices.

+   File Name:          15.4.4.5.js
+   ECMA Section:       Array.prototype.sort(comparefn)
+   Description:
+
+   This test file tests cases in which the compare function is not supplied.
+
+   The elements of this array are sorted. The sort is not necessarily stable.
+   If comparefn is provided, it should be a function that accepts two arguments
+   x and y and returns a negative value if x < y, zero if x = y, or a positive
+   value if x > y.
+
+   1.   Call the [[Get]] method of this object with argument "length".
+   2.   Call ToUint32(Result(1)).
+   1.  Perform an implementation-dependent sequence of calls to the
+   [[Get]] , [[Put]], and [[Delete]] methods of this object and
+   toSortCompare (described below), where the first argument for each call
+   to [[Get]], [[Put]] , or [[Delete]] is a nonnegative integer less
+   than Result(2) and where the arguments for calls to SortCompare are
+   results of previous calls to the [[Get]] method. After this sequence
+   is complete, this object must have the following two properties.
+   (1) There must be some mathematical permutation of the nonnegative
+   integers less than Result(2), such that for every nonnegative integer
+   j less than Result(2), if property old[j] existed, then new[(j)] is
+   exactly the same value as old[j],. but if property old[j] did not exist,
+   then new[(j)] either does not exist or exists with value undefined.
+   (2) If comparefn is not supplied or is a consistent comparison
+   function for the elements of this array, then for all nonnegative
+   integers j and k, each less than Result(2), if old[j] compares less
+   than old[k] (see SortCompare below), then (j) < (k). Here we use the
+   notation old[j] to refer to the hypothetical result of calling the [
+   [Get]] method of this object with argument j before this step is
+   executed, and the notation new[j] to refer to the hypothetical result
+   of calling the [[Get]] method of this object with argument j after this
+   step has been completely executed. A function is a consistent
+   comparison function for a set of values if (a) for any two of those
+   values (possibly the same value) considered as an ordered pair, it
+   always returns the same value when given that pair of values as its
+   two arguments, and the result of applying ToNumber to this value is
+   not NaN; (b) when considered as a relation, where the pair (x, y) is
+   considered to be in the relation if and only if applying the function
+   to x and y and then applying ToNumber to the result produces a
+   negative value, this relation is a partial order; and (c) when
+   considered as a different relation, where the pair (x, y) is considered
+   to be in the relation if and only if applying the function to x and y
+   and then applying ToNumber to the result produces a zero value (of either
+   sign), this relation is an equivalence relation. In this context, the
+   phrase "x compares less than y" means applying Result(2) to x and y and
+   then applying ToNumber to the result produces a negative value.
+   3.Return this object.
+
+   When the SortCompare operator is called with two arguments x and y, the following steps are taken:
+   1.If x and y are both undefined, return +0.
+   2.If x is undefined, return 1.
+   3.If y is undefined, return 1.
+   4.If the argument comparefn was not provided in the call to sort, go to step 7.
+   5.Call comparefn with arguments x and y.
+   6.Return Result(5).
+   7.Call ToString(x).
+   8.Call ToString(y).
+   9.If Result(7) < Result(8), return 1.
+   10.If Result(7) > Result(8), return 1.
+   11.Return +0.
+
+   Note that, because undefined always compared greater than any other value, undefined and nonexistent
+   property values always sort to the end of the result. It is implementation-dependent whether or not such
+   properties will exist or not at the end of the array when the sort is concluded.
+
+   Note that the sort function is intentionally generic; it does not require that its this value be an Array object.
+   Therefore it can be transferred to other kinds of objects for use as a method. Whether the sort function can be
+   applied successfully to a host object is implementation dependent .

+   to [[Get]], [[Put]] , or [[Delete]] is a nonnegative integer less
+   than Result(2) and where the arguments for calls to SortCompare are
+   results of previous calls to the [[Get]] method. After this sequence
+   is complete, this object must have the following two properties.
+   (1) There must be some mathematical permutation of the nonnegative
+   integers less than Result(2), such that for every nonnegative integer
+   j less than Result(2), if property old[j] existed, then new[(j)] is
+   exactly the same value as old[j],. but if property old[j] did not exist,
+   then new[(j)] either does not exist or exists with value undefined.
+   (2) If comparefn is not supplied or is a consistent comparison
+   function for the elements of this array, then for all nonnegative
+   integers j and k, each less than Result(2), if old[j] compares less
+   than old[k] (see SortCompare below), then (j) < (k). Here we use the
+   notation old[j] to refer to the hypothetical result of calling the [
+   [Get]] method of this object with argument j before this step is
+   executed, and the notation new[j] to refer to the hypothetical result
+   of calling the [[Get]] method of this object with argument j after this
+   step has been completely executed. A function is a consistent
+   comparison function for a set of values if (a) for any two of those
+   values (possibly the same value) considered as an ordered pair, it
+   always returns the same value when given that pair of values as its
+   two arguments, and the result of applying ToNumber to this value is
+   not NaN; (b) when considered as a relation, where the pair (x, y) is
+   considered to be in the relation if and only if applying the function
+   to x and y and then applying ToNumber to the result produces a
+   negative value, this relation is a partial order; and (c) when
+   considered as a different relation, where the pair (x, y) is considered
+   to be in the relation if and only if applying the function to x and y
+   and then applying ToNumber to the result produces a zero value (of either
+   sign), this relation is an equivalence relation. In this context, the
+   phrase "x compares less than y" means applying Result(2) to x and y and
+   then applying ToNumber to the result produces a negative value.
+   3.Return this object.
+
+   When the SortCompare operator is called with two arguments x and y, the following steps are taken:
+   1.If x and y are both undefined, return +0.
+   2.If x is undefined, return 1.
+   3.If y is undefined, return 1.
+   4.If the argument comparefn was not provided in the call to sort, go to step 7.
+   5.Call comparefn with arguments x and y.
+   6.Return Result(5).
+   7.Call ToString(x).
+   8.Call ToString(y).
+   9.If Result(7) < Result(8), return 1.
+   10.If Result(7) > Result(8), return 1.
+   11.Return +0.
+
+   Note that, because undefined always compared greater than any other value, undefined and nonexistent
+   property values always sort to the end of the result. It is implementation-dependent whether or not such
+   properties will exist or not at the end of the array when the sort is concluded.
+
+   Note that the sort function is intentionally generic; it does not require that its this value be an Array object.
+   Therefore it can be transferred to other kinds of objects for use as a method. Whether the sort function can be
+   applied successfully to a host object is implementation dependent .

+   this does not refer to an object for which the value of the internal
+   [[Class]] property is "Boolean". Also, the phrase "this boolean value"
+   refers to the boolean value represented by this Boolean object, that is,
+   the value of the internal [[Value]] property of this Boolean object.

+   ECMA Section:       15.9.3.1 new Date (year, month, date, hours, minutes, seconds, ms)
+   Description:        The [[Prototype]] property of the newly constructed
+   object is set to the original Date prototype object,
+   the one that is the initial value of Date.prototype.
+
+   The [[Class]] property of the newly constructed object
+   is set as follows:

+   2. Call ToNumber(month)
+   3. Call ToNumber(date)
+   4. Call ToNumber(hours)
+   5. Call ToNumber(minutes)
+   6. Call ToNumber(seconds)
+   7. Call ToNumber(ms)
+   8.  If Result(1) is NaN and 0 <= ToInteger(Result(1)) <=
+   99, Result(8) is 1900+ToInteger(Result(1)); otherwise,
+   Result(8) is Result(1)
+   9.  Compute MakeDay(Result(8), Result(2), Result(3)
+   10. Compute MakeTime(Result(4), Result(5), Result(6),
+   Result(7)
+   11. Compute MakeDate(Result(9), Result(10))
+   12. Set the [[Value]] property of the newly constructed
+   object to TimeClip(UTC(Result(11))).
+
+
+   This tests the returned value of a newly constructed
+   Date object.

+   the one that is the initial value of Date.prototype.
+
+   The [[Class]] property of the newly constructed object

+   2. Call ToNumber(month)
+   3. Call ToNumber(date)
+   4. Call ToNumber(hours)
+   5. Call ToNumber(minutes)
+   6. Call ToNumber(seconds)
+   7. Call ToNumber(ms)
+   8.  If Result(1)is NaN and 0 <= ToInteger(Result(1)) <=
+   99, Result(8) is 1900+ToInteger(Result(1)); otherwise,
+   Result(8) is Result(1)

+   new Date( value )
+   Description:        The [[Prototype]] property of the newly constructed
+   object is set to the original Date prototype object,
+   the one that is the initial valiue of Date.prototype.
+
+   The [[Class]] property of the newly constructed object is
+   set to "Date".
+
+   The [[Value]] property of the newly constructed object is
+   set as follows:
+
+   1. Call ToPrimitive(value)
+   2. If Type( Result(1) ) is String, then go to step 5.
+   3. Let V be  ToNumber( Result(1) ).
+   4. Set the [[Value]] property of the newly constructed
+   object to TimeClip(V) and return.
+   5. Parse Result(1) as a date, in exactly the same manner
+   as for the parse method.  Let V be the time value for
+   this date.
+   6. Go to step 4.

+   File Name:          15.9.4.2.js
+   ECMA Section:       15.9.4.2 Date.parse()
+   Description:        The parse() function applies the to ToString() operator
+   to its argument and interprets the resulting string as
+   a date.  It returns a number, the UTC time value
+   corresponding to the date.
+
+   The string may be interpreted as a local time, a UTC
+   time, or a time in some other time zone, depending on
+   the contents of the string.
+
+   (need to test strings containing stuff with the time
+   zone specified, and verify that parse() returns the
+   correct GMT time)
+
+   so for any Date object x, all of these things should
+   be equal:
+
+   value                       tested in function:
+   x.valueOf()                 test_value()
+   Date.parse(x.toString())    test_tostring()
+   Date.parse(x.toGMTString()) test_togmt()
+
+   Date.parse(x.toLocaleString()) is not required to
+   produce the same number value as the preceding three
+   expressions.  in general the value produced by
+   Date.parse is implementation dependent when given any
+   string value that could not be produced in that
+   implementation by the toString or toGMTString method.
+
+   value                           tested in function:
+   Date.parse( x.toLocaleString()) test_tolocale()

+   ECMA Section:       15.9.5.2 Date.prototype.toString
+   Description:
+   This function returns a string value. The contents of the string are
+   implementation dependent, but are intended to represent the Date in a
+   convenient, human-readable form in the current time zone.
+
+   The toString function is not generic; it generates a runtime error if its
+   this value is not a Date object. Therefore it cannot be transferred to
+   other kinds of objects for use as a method.

+   [[Class]] property is "Date". Also, the phrase "this time value" refers
+   to the number value for the time represented by this Date object, that is,
+   the value of the internal [[Value]] property of this Date object.

+   Description:
+
+   For each formal parameter, as defined in the FormalParameterList, create
+   a property of the variable object whose name is the Identifier and whose
+   attributes are determined by the type of code. The values of the
+   parameters are supplied by the caller. If the caller supplies fewer
+   parameter values than there are formal parameters, the extra formal
+   parameters have value undefined. If two or more formal parameters share
+   the same name, hence the same property, the corresponding property is
+   given the value that was supplied for the last parameter with this name.
+   If the value of this last parameter was not supplied by the caller,
+   the value of the corresponding property is undefined.

+   Description:
+   Every execution context has associated with it a scope chain. This is
+   logically a list of objects that are searched when binding an Identifier.
+   When control enters an execution context, the scope chain is created and
+   is populated with an initial set of objects, depending on the type of
+   code. When control leaves the execution context, the scope chain is
+   destroyed.
+
+   During execution, the scope chain of the execution context is affected
+   only by WithStatement. When execution enters a with block, the object
+   specified in the with statement is added to the front of the scope chain.
+   When execution leaves a with block, whether normally or via a break or
+   continue statement, the object is removed from the scope chain. The object
+   being removed will always be the first object in the scope chain.
+
+   During execution, the syntactic production PrimaryExpression : Identifier
+   is evaluated using the following algorithm:
+
+   1.  Get the next object in the scope chain. If there isn't one, go to step 5.
+   2.  Call the [[HasProperty]] method of Result(l), passing the Identifier as
+   the property.
+   3.  If Result(2) is true, return a value of type Reference whose base object
+   is Result(l) and whose property name is the Identifier.
+   4.  Go to step 1.
+   5.  Return a value of type Reference whose base object is null and whose
+   property name is the Identifier.
+   The result of binding an identifier is always a value of type Reference with
+   its member name component equal to the identifier string.

+   ECMA Section:       10.1.4 Scope Chain and Identifier Resolution
+   Description:
+   Every execution context has associated with it a scope chain. This is
+   logically a list of objects that are searched when binding an Identifier.
+   When control enters an execution context, the scope chain is created and
+   is populated with an initial set of objects, depending on the type of
+   code. When control leaves the execution context, the scope chain is
+   destroyed.
+
+   During execution, the scope chain of the execution context is affected
+   only by WithStatement. When execution enters a with block, the object
+   specified in the with statement is added to the front of the scope chain.
+   When execution leaves a with block, whether normally or via a break or
+   continue statement, the object is removed from the scope chain. The object
+   being removed will always be the first object in the scope chain.
+
+   During execution, the syntactic production PrimaryExpression : Identifier
+   is evaluated using the following algorithm:
+
+   1.  Get the next object in the scope chain. If there isn't one, go to step 5.
+   2.  Call the [[HasProperty]] method of Result(l), passing the Identifier as
+   the property.
+   3.  If Result(2) is true, return a value of type Reference whose base object
+   is Result(l) and whose property name is the Identifier.
+   4.  Go to step 1.
+   5.  Return a value of type Reference whose base object is null and whose
+   property name is the Identifier.
+   The result of binding an identifier is always a value of type Reference with
+   its member name component equal to the identifier string.

+

+
+   As control enters execution contexts, and as ECMAScript code is executed,
+   additional properties may be added to the global object and the initial
+   properties may be changed.

+   File Name:          10.1.8-2
+   ECMA Section:       Arguments Object
+   Description:
+
+   When control enters an execution context for declared function code,
+   anonymous code, or implementation-supplied code, an arguments object is
+   created and initialized as follows:
+
+   The [[Prototype]] of the arguments object is to the original Object
+   prototype object, the one that is the initial value of Object.prototype
+   (section 15.2.3.1).
+
+   A property is created with name callee and property attributes {DontEnum}.
+   The initial value of this property is the function object being executed.
+   This allows anonymous functions to be recursive.
+
+   A property is created with name length and property attributes {DontEnum}.
+   The initial value of this property is the number of actual parameter values
+   supplied by the caller.
+
+   For each non-negative integer, iarg, less than the value of the length
+   property, a property is created with name ToString(iarg) and property
+   attributes { DontEnum }. The initial value of this property is the value
+   of the corresponding actual parameter supplied by the caller. The first
+   actual parameter value corresponds to iarg = 0, the second to iarg = 1 and
+   so on. In the case when iarg is less than the number of formal parameters
+   for the function object, this property shares its value with the
+   corresponding property of the activation object. This means that changing
+   this property changes the corresponding property of the activation object
+   and vice versa. The value sharing mechanism depends on the implementation.

+   the activation object as the variable object and using property attributes
+   { DontDelete }. The caller provides the this value. If the this value
+   provided by the caller is not an object (including the case where it is
+   null), then the this value is the global object.

+   11.13.2 Compound assignment ( op= )
+
+   The production AssignmentExpression :
+   LeftHandSideExpression @ = AssignmentExpression, where @ represents one of
+   the operators indicated above, is evaluated as follows:
+
+   1.  Evaluate LeftHandSideExpression.
+   2.  Call GetValue(Result(1)).
+   3.  Evaluate AssignmentExpression.
+   4.  Call GetValue(Result(3)).
+   5.  Apply operator @ to Result(2) and Result(4).
+   6.  Call PutValue(Result(1), Result(5)).
+   7.  Return Result(5).

+   ECMA Section:       11.2.1 Property Accessors
+   Description:
+
+   Properties are accessed by name, using either the dot notation:
+   MemberExpression . Identifier
+   CallExpression . Identifier
+
+   or the bracket notation:    MemberExpression [ Expression ]
+   CallExpression [ Expression ]
+
+   The dot notation is explained by the following syntactic conversion:
+   MemberExpression . Identifier
+   is identical in its behavior to
+   MemberExpression [ <identifier-string> ]
+   and similarly
+   CallExpression . Identifier
+   is identical in its behavior to
+   CallExpression [ <identifier-string> ]
+   where <identifier-string> is a string literal containing the same sequence
+   of characters as the Identifier.
+
+   The production MemberExpression : MemberExpression [ Expression ] is
+   evaluated as follows:
+
+   1.  Evaluate MemberExpression.
+   2.  Call GetValue(Result(1)).
+   3.  Evaluate Expression.
+   4.  Call GetValue(Result(3)).
+   5.  Call ToObject(Result(2)).
+   6.  Call ToString(Result(4)).
+   7.  Return a value of type Reference whose base object is Result(5) and
+   whose property name is Result(6).
+
+   The production CallExpression : CallExpression [ Expression ] is evaluated
+   in exactly the same manner, except that the contained CallExpression is
+   evaluated in step 1.

+   Properties are accessed by name, using either the dot notation:
+   MemberExpression . Identifier
+   CallExpression . Identifier
+
+   or the bracket notation:    MemberExpression [ Expression ]
+   CallExpression [ Expression ]
+
+   The dot notation is explained by the following syntactic conversion:
+   MemberExpression . Identifier
+   is identical in its behavior to
+   MemberExpression [ <identifier-string> ]
+   and similarly
+   CallExpression . Identifier
+   is identical in its behavior to
+   CallExpression [ <identifier-string> ]
+   where <identifier-string> is a string literal containing the same sequence
+   of characters as the Identifier.
+
+   The production MemberExpression : MemberExpression [ Expression ] is
+   evaluated as follows:
+
+   1.  Evaluate MemberExpression.
+   2.  Call GetValue(Result(1)).
+   3.  Evaluate Expression.
+   4.  Call GetValue(Result(3)).
+   5.  Call ToObject(Result(2)).
+   6.  Call ToString(Result(4)).
+   7.  Return a value of type Reference whose base object is Result(5) and
+   whose property name is Result(6).
+
+   The production CallExpression : CallExpression [ Expression ] is evaluated
+   in exactly the same manner, except that the contained CallExpression is
+   evaluated in step 1.

+   ECMA Section:       11.2.1 Property Accessors
+   Description:
+
+   Properties are accessed by name, using either the dot notation:
+   MemberExpression . Identifier
+   CallExpression . Identifier
+
+   or the bracket notation:    MemberExpression [ Expression ]
+   CallExpression [ Expression ]
+
+   The dot notation is explained by the following syntactic conversion:
+   MemberExpression . Identifier
+   is identical in its behavior to
+   MemberExpression [ <identifier-string> ]
+   and similarly
+   CallExpression . Identifier
+   is identical in its behavior to
+   CallExpression [ <identifier-string> ]
+   where <identifier-string> is a string literal containing the same sequence
+   of characters as the Identifier.
+
+   The production MemberExpression : MemberExpression [ Expression ] is
+   evaluated as follows:
+
+   1.  Evaluate MemberExpression.
+   2.  Call GetValue(Result(1)).
+   3.  Evaluate Expression.
+   4.  Call GetValue(Result(3)).
+   5.  Call ToObject(Result(2)).
+   6.  Call ToString(Result(4)).
+   7.  Return a value of type Reference whose base object is Result(5) and
+   whose property name is Result(6).
+
+   The production CallExpression : CallExpression [ Expression ] is evaluated
+   in exactly the same manner, except that the contained CallExpression is
+   evaluated in step 1.

+   7.If Result(6) is an activation object, Result(7) is null. Otherwise, Result(7) is

+   8.Call the [[Call]] method on Result(3), providing Result(7) as the this value

+   ECMA Section:       11.5.1 Applying the * operator
+   Description:
+
+   11.5.1 Applying the * operator
+
+   The * operator performs multiplication, producing the product of its
+   operands. Multiplication is commutative. Multiplication is not always
+   associative in ECMAScript, because of finite precision.
+
+   The result of a floating-point multiplication is governed by the rules
+   of IEEE 754 double-precision arithmetic:
+
+   If either operand is NaN, the result is NaN.
+   The sign of the result is positive if both operands have the same sign,
+   negative if the operands have different signs.
+   Multiplication of an infinity by a zero results in NaN.
+   Multiplication of an infinity by an infinity results in an infinity.
+   The sign is determined by the rule already stated above.
+   Multiplication of an infinity by a finite non-zero value results in a
+   signed infinity. The sign is determined by the rule already stated above.
+   In the remaining cases, where neither an infinity or NaN is involved, the
+   product is computed and rounded to the nearest representable value using IEEE
+   754 round-to-nearest mode. If the magnitude is too large to represent,
+   the result is then an infinity of appropriate sign. If the magnitude is
+   oo small to represent, the result is then a zero
+   of appropriate sign. The ECMAScript language requires support of gradual
+   underflow as defined by IEEE 754.

+   File Name:          11.5.2.js
+   ECMA Section:       11.5.2 Applying the / operator
+   Description:
+
+   The / operator performs division, producing the quotient of its operands.
+   The left operand is the dividend and the right operand is the divisor.
+   ECMAScript does not perform integer division. The operands and result of all
+   division operations are double-precision floating-point numbers.
+   The result of division is determined by the specification of IEEE 754 arithmetic:
+
+   If either operand is NaN, the result is NaN.
+   The sign of the result is positive if both operands have the same sign, negative if the operands have different
+   signs.
+   Division of an infinity by an infinity results in NaN.
+   Division of an infinity by a zero results in an infinity. The sign is determined by the rule already stated above.
+   Division of an infinity by a non-zero finite value results in a signed infinity. The sign is determined by the rule
+   already stated above.
+   Division of a finite value by an infinity results in zero. The sign is determined by the rule already stated above.
+   Division of a zero by a zero results in NaN; division of zero by any other finite value results in zero, with the sign
+   determined by the rule already stated above.
+   Division of a non-zero finite value by a zero results in a signed infinity. The sign is determined by the rule
+   already stated above.
+   In the remaining cases, where neither an infinity, nor a zero, nor NaN is involved, the quotient is computed and
+   rounded to the nearest representable value using IEEE 754 round-to-nearest mode. If the magnitude is too
+   large to represent, we say the operation overflows; the result is then an infinity of appropriate sign. If the
+   magnitude is too small to represent, we say the operation underflows and the result is a zero of the appropriate
+   sign. The ECMAScript language requires support of gradual underflow as defined by IEEE 754.

+   File Name:          11.5.3.js
+   ECMA Section:       11.5.3 Applying the % operator
+   Description:
+
+   The binary % operator is said to yield the remainder of its operands from
+   an implied division; the left operand is the dividend and the right operand
+   is the divisor. In C and C++, the remainder operator accepts only integral
+   operands, but in ECMAScript, it also accepts floating-point operands.
+
+   The result of a floating-point remainder operation as computed by the %
+   operator is not the same as the "remainder" operation defined by IEEE 754.
+   The IEEE 754 "remainder" operation computes the remainder from a rounding
+   division, not a truncating division, and so its behavior is not analogous
+   to that of the usual integer remainder operator. Instead the ECMAScript
+   language defines % on floating-point operations to behave in a manner
+   analogous to that of the Java integer remainder operator; this may be
+   compared with the C library function fmod.
+
+   The result of a ECMAScript floating-point remainder operation is determined by the rules of IEEE arithmetic:
+
+   If either operand is NaN, the result is NaN.
+   The sign of the result equals the sign of the dividend.
+   If the dividend is an infinity, or the divisor is a zero, or both, the result is NaN.
+   If the dividend is finite and the divisor is an infinity, the result equals the dividend.
+   If the dividend is a zero and the divisor is finite, the result is the same as the dividend.
+   In the remaining cases, where neither an infinity, nor a zero, nor NaN is involved, the floating-point remainder r
+   from a dividend n and a divisor d is defined by the mathematical relation r = n (d * q) where q is an integer that
+   is negative only if n/d is negative and positive only if n/d is positive, and whose magnitude is as large as
+   possible without exceeding the magnitude of the true mathematical quotient of n and d.

+   File Name:          11.6.3.js
+   ECMA Section:       11.6.3 Applying the additive operators
+   (+, -) to numbers
+   Description:
+   The + operator performs addition when applied to two operands of numeric
+   type, producing the sum of the operands. The - operator performs
+   subtraction, producing the difference of two numeric operands.
+
+   Addition is a commutative operation, but not always associative.
+
+   The result of an addition is determined using the rules of IEEE 754
+   double-precision arithmetic:
+
+   If either operand is NaN, the result is NaN.
+   The sum of two infinities of opposite sign is NaN.
+   The sum of two infinities of the same sign is the infinity of that sign.
+   The sum of an infinity and a finite value is equal to the infinite operand.
+   The sum of two negative zeros is 0. The sum of two positive zeros, or of
+   two zeros of opposite sign, is +0.
+   The sum of a zero and a nonzero finite value is equal to the nonzero
+   operand.
+   The sum of two nonzero finite values of the same magnitude and opposite
+   sign is +0.
+   In the remaining cases, where neither an infinity, nor a zero, nor NaN is
+   involved, and the operands have the same sign or have different
+   magnitudes, the sum is computed and rounded to the nearest
+   representable value using IEEE 754 round-to-nearest mode. If the
+   magnitude is too large to represent, the operation overflows and
+   the result is then an infinity of appropriate sign. The ECMAScript
+   language requires support of gradual underflow as defined by IEEE 754.

+   ECMA Section:       11.7.3  The unsigned right shift operator ( >>> )
+   Description:
+   11.7.3 The unsigned right shift operator ( >>> )
+   Performs a zero-filling bitwise right shift operation on the left argument
+   by the amount specified by the right argument.
+
+   The production ShiftExpression : ShiftExpression >>> AdditiveExpression is
+   evaluated as follows:
+
+   1.  Evaluate ShiftExpression.
+   2.  Call GetValue(Result(1)).
+   3.  Evaluate AdditiveExpression.
+   4.  Call GetValue(Result(3)).
+   5.  Call ToUint32(Result(2)).
+   6.  Call ToUint32(Result(4)).
+   7.  Mask out all but the least significant 5 bits of Result(6), that is,
+   compute Result(6) & 0x1F.
+   8.  Perform zero-filling right shift of Result(5) by Result(7) bits.
+   Vacated bits are filled with zero. The result is an unsigned 32 bit
+   integer.
+   9.  Return Result(8).

+
+   Description:
+
+   15.3.5.1 length
+
+   The value of the length property is usually an integer that indicates
+   the "typical" number of arguments expected by the function. However,
+   the language permits the function to be invoked with some other number
+   of arguments. The behavior of a function when invoked on a number of
+   arguments other than the number specified by its length property depends
+   on the function.
+
+   15.3.5.2 prototype
+   The value of the prototype property is used to initialize the internal [[
+   Prototype]] property of a newly created object before the Function object
+   is invoked as a constructor for that newly created object.
+
+   15.3.5.3 arguments
+
+   The value of the arguments property is normally null if there is no
+   outstanding invocation of the function in progress (that is, the function has been called
+   but has not yet returned). When a non-internal Function object (15.3.2.1) is invoked, its
+   arguments property is "dynamically bound" to a newly created object that contains the
+   arguments on which it was invoked (see 10.1.6 and 10.1.8). Note that the use of this
+   property is discouraged; it is provided principally for compatibility with existing old code.

+   File Name:          15.1.2.2-1.js
+   ECMA Section:       15.1.2.2 Function properties of the global object
+   parseInt( string, radix )
+
+   Description:
+
+   The parseInt function produces an integer value dictated by intepretation
+   of the contents of the string argument according to the specified radix.
+
+   When the parseInt function is called, the following steps are taken:
+
+   1.   Call ToString(string).
+   2.   Compute a substring of Result(1) consisting of the leftmost character
+   that is not a StrWhiteSpaceChar and all characters to the right of
+   that character. (In other words, remove leading whitespace.)
+   3.   Let sign be 1.
+   4.   If Result(2) is not empty and the first character of Result(2) is a
+   minus sign -, let sign be -1.
+   5.   If Result(2) is not empty and the first character of Result(2) is a
+   plus sign + or a minus sign -, then Result(5) is the substring of
+   Result(2) produced by removing the first character; otherwise, Result(5)
+   is Result(2).
+   6.   If the radix argument is not supplied, go to step 12.
+   7.   Call ToInt32(radix).
+   8.   If Result(7) is zero, go to step 12; otherwise, if Result(7) < 2 or
+   Result(7) > 36, return NaN.
+   9.   Let R be Result(7).
+   10.   If R = 16 and the length of Result(5) is at least 2 and the first two
+   characters of Result(5) are either "0x" or "0X", let S be the substring
+   of Result(5) consisting of all but the first two characters; otherwise,
+   let S be Result(5).
+   11.   Go to step 22.
+   12.   If Result(5) is empty or the first character of Result(5) is not 0,
+   go to step 20.
+   13.   If the length of Result(5) is at least 2 and the second character of
+   Result(5) is x or X, go to step 17.
+   14.   Let R be 8.
+   15.   Let S be Result(5).
+   16.   Go to step 22.
+   17.   Let R be 16.
+   18.   Let S be the substring of Result(5) consisting of all but the first
+   two characters.
+   19.   Go to step 22.
+   20.   Let R be 10.
+   21.   Let S be Result(5).
+   22.   If S contains any character that is not a radix-R digit, then let Z be
+   the substring of S consisting of all characters to the left of the
+   leftmost such character; otherwise, let Z be S.
+   23.   If Z is empty, return NaN.
+   24.   Compute the mathematical integer value that is represented by Z in
+   radix-R notation. (But if R is 10 and Z contains more than 20
+   significant digits, every digit after the 20th may be replaced by a 0
+   digit, at the option of the implementation; and if R is not 2, 4, 8,
+   10, 16, or 32, then Result(24) may be an implementation-dependent
+   approximation to the mathematical integer value that is represented
+   by Z in radix-R notation.)
+   25.   Compute the number value for Result(24).
+   26.   Return sign Result(25).
+
+   Note that parseInt may interpret only a leading portion of the string as
+   an integer value; it ignores any characters that cannot be interpreted as
+   part of the notation of an integer, and no indication is given that any
+   such characters were ignored.

+   ECMA Section:       15.1.2.3 Function properties of the global object:
+   parseFloat( string )
+
+   Description:        The parseFloat function produces a number value dictated
+   by the interpretation of the contents of the string
+   argument defined as a decimal literal.
+
+   When the parseFloat function is called, the following
+   steps are taken:
+
+   1.  Call ToString( string ).
+   2.  Remove leading whitespace Result(1).
+   3.  If neither Result(2) nor any prefix of Result(2)
+   satisfies the syntax of a StrDecimalLiteral,
+   return NaN.
+   4.  Compute the longest prefix of Result(2) which might
+   be Resusult(2) itself, that satisfies the syntax of
+   a StrDecimalLiteral
+   5.  Return the number value for the MV of Result(4).
+
+   Note that parseFloate may interpret only a leading
+   portion of the string as a number value; it ignores any
+   characters that cannot be interpreted as part of the
+   notation of a decimal literal, and no indication is given
+   that such characters were ignored.

+   File Name:          15.1.2.3-2.js
+   ECMA Section:       15.1.2.3 Function properties of the global object:
+   parseFloat( string )
+
+   Description:        The parseFloat function produces a number value dictated
+   by the interpretation of the contents of the string
+   argument defined as a decimal literal.
+
+   When the parseFloat function is called, the following
+   steps are taken:
+
+   1.  Call ToString( string ).
+   2.  Remove leading whitespace Result(1).
+   3.  If neither Result(2) nor any prefix of Result(2)
+   satisfies the syntax of a StrDecimalLiteral,
+   return NaN.
+   4.  Compute the longest prefix of Result(2) which might
+   be Resusult(2) itself, that satisfies the syntax of
+   a StrDecimalLiteral
+   5.  Return the number value for the MV of Result(4).
+
+   Note that parseFloate may interpret only a leading
+   portion of the string as a number value; it ignores any
+   characters that cannot be interpreted as part of the
+   notation of a decimal literal, and no indication is given
+   that such characters were ignored.

+   File Name:          15.1.2.4.js
+   ECMA Section:       15.1.2.4  Function properties of the global object
+   escape( string )
+
+   Description:
+   The escape function computes a new version of a string value in which
+   certain characters have been replaced by a hexadecimal escape sequence.
+   The result thus contains no special characters that might have special
+   meaning within a URL.
+
+   For characters whose Unicode encoding is 0xFF or less, a two-digit
+   escape sequence of the form %xx is used in accordance with RFC1738.
+   For characters whose Unicode encoding is greater than 0xFF, a four-
+   digit escape sequence of the form %uxxxx is used.
+
+   When the escape function is called with one argument string, the
+   following steps are taken:
+
+   1.  Call ToString(string).
+   2.  Compute the number of characters in Result(1).
+   3.  Let R be the empty string.
+   4.  Let k be 0.
+   5.  If k equals Result(2), return R.
+   6.  Get the character at position k within Result(1).
+   7.  If Result(6) is one of the 69 nonblank ASCII characters
+   ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz
+   0123456789 @*_+-./, go to step 14.
+   8.  Compute the 16-bit unsigned integer that is the Unicode character
+   encoding of Result(6).
+   9.  If Result(8), is less than 256, go to step 12.
+   10.  Let S be a string containing six characters "%uwxyz" where wxyz are
+   four hexadecimal digits encoding the value of Result(8).
+   11.  Go to step 15.
+   12.  Let S be a string containing three characters "%xy" where xy are two
+   hexadecimal digits encoding the value of Result(8).
+   13.  Go to step 15.
+   14.  Let S be a string containing the single character Result(6).
+   15.  Let R be a new string value computed by concatenating the previous value
+   of R and S.
+   16.  Increase k by 1.
+   17.  Go to step 5.

+   ECMA Section:       15.1.2.5  Function properties of the global object
+   unescape( string )
+   Description:
+
+   This tests the cases where there are fewer than 4 characters following "%u",
+   or fewer than 2 characters following "%" or "%u".
+
+   The unescape function computes a new version of a string value in which
+   each escape sequences of the sort that might be introduced by the escape
+   function is replaced with the character that it represents.
+
+   When the unescape function is called with one argument string, the
+   following steps are taken:
+
+   1.  Call ToString(string).
+   2.  Compute the number of characters in Result(1).
+   3.  Let R be the empty string.
+   4.  Let k be 0.
+   5.  If k equals Result(2), return R.
+   6.  Let c be the character at position k within Result(1).
+   7.  If c is not %, go to step 18.
+   8.  If k is greater than Result(2)-6, go to step 14.
+   9.  If the character at position k+1 within result(1) is not u, go to step
+   14.
+   10. If the four characters at positions k+2, k+3, k+4, and k+5 within
+   Result(1) are not all hexadecimal digits, go to step 14.
+   11. Let c be the character whose Unicode encoding is the integer represented
+   by the four hexadecimal digits at positions k+2, k+3, k+4, and k+5
+   within Result(1).
+   12. Increase k by 5.
+   13. Go to step 18.
+   14. If k is greater than Result(2)-3, go to step 18.
+   15. If the two characters at positions k+1 and k+2 within Result(1) are not
+   both hexadecimal digits, go to step 18.
+   16. Let c be the character whose Unicode encoding is the integer represented
+   by two zeroes plus the two hexadecimal digits at positions k+1 and k+2
+   within Result(1).
+   17. Increase k by 2.
+   18. Let R be a new string value computed by concatenating the previous value
+   of R and c.
+   19. Increase k by 1.
+   20. Go to step 5.

+
+   Waldemar's comments:
+
+   A numeric literal that starts with either '08' or '09' is interpreted as a
+   decimal literal; it should be an error instead.  (Strictly speaking, according
+   to ECMA v1 such literals should be interpreted as two integers -- a zero
+   followed by a decimal number whose first digit is 8 or 9, but this is a bug in
+   ECMA that will be fixed in v2.  In any case, there is no place in the grammar
+   where two consecutive numbers would be legal.)

+   ECMA Section:       15.8.2.15  Math.round(x)
+   Description:        return the greatest number value that is closest to the
+   argument and is an integer.  if two integers are equally
+   close to the argument. then the result is the number value
+   that is closer to Infinity.  if the argument is an integer,
+   return the argument.
+   special cases:
+   - if x is NaN       return NaN
+   - if x = +0         return +0
+   - if x = -0          return -0
+   - if x = Infinity   return Infinity
+   - if x = -Infinity  return -Infinity
+   - if 0 < x < 0.5    return 0
+   - if -0.5 <= x < 0  return -0
+   example:
+   Math.round( 3.5 ) == 4
+   Math.round( -3.5 ) == 3
+   also:
+   - Math.round(x) == Math.floor( x + 0.5 )

+
+   1.  If value is null or undefined, create and return a
+   new object with no properties other than internal
+   properties exactly as if the object constructor
+   had been called on that same value (15.2.2.1).
+   2.  Return ToObject (value), whose rules are:
+
+   undefined   generate a runtime error
+   null        generate a runtime error
+   boolean     create a new Boolean object whose default
+   value is the value of the boolean.
+   number      Create a new Number object whose default
+   value is the value of the number.
+   string      Create a new String object whose default
+   value is the value of the string.
+   object      Return the input argument (no conversion).

+   Description:        When Object is called as a function rather than as a
+   constructor, the following steps are taken:
+
+   1.  If value is null or undefined, create and return a
+   new object with no proerties other than internal
+   properties exactly as if the object constructor
+   had been called on that same value (15.2.2.1).
+   2.  Return ToObject (value), whose rules are:
+
+   undefined   generate a runtime error
+   null        generate a runtime error
+   boolean     create a new Boolean object whose default
+   value is the value of the boolean.
+   number      Create a new Number object whose default
+   value is the value of the number.
+   string      Create a new String object whose default
+   value is the value of the string.
+   object      Return the input argument (no conversion).

+
+   1.If the type of the value is not Object, go to step 4.
+   2.If the value is a native ECMAScript object, do not create a new object; simply return value.
+   3.If the value is a host object, then actions are taken and a result is returned in an

+   4.If the type of the value is String, return ToObject(value).
+   5.If the type of the value is Boolean, return ToObject(value).
+   6.If the type of the value is Number, return ToObject(value).
+   7.(The type of the value must be Null or Undefined.) Create a new native ECMAScript object.

+   File Name:          6-1.js
+   ECMA Section:       Source Text
+   Description:
+
+   ECMAScript source text is represented as a sequence of characters
+   representable using the Unicode version 2.0 character encoding.
+
+   SourceCharacter ::
+   any Unicode character
+
+   However, it is possible to represent every ECMAScript program using
+   only ASCII characters (which are equivalent to the first 128 Unicode
+   characters). Non-ASCII Unicode characters may appear only within comments
+   and string literals. In string literals, any Unicode character may also be
+   expressed as a Unicode escape sequence consisting of six ASCII characters,
+   namely \u plus four hexadecimal digits. Within a comment, such an escape
+   sequence is effectively ignored as part of the comment. Within a string
+   literal, the Unicode escape sequence contributes one character to the string
+   value of the literal.
+
+   Note that ECMAScript differs from the Java programming language in the
+   behavior of Unicode escape sequences. In a Java program, if the Unicode escape
+   sequence \u000A, for example, occurs within a single-line comment, it is
+   interpreted as a line terminator (Unicode character 000A is line feed) and
+   therefore the next character is not part of the comment. Similarly, if the
+   Unicode escape sequence \u000A occurs within a string literal in a Java
+   program, it is likewise interpreted as a line terminator, which is not
+   allowed within a string literal-one must write \n instead of \u000A to
+   cause a line feed to be part of the string value of a string literal. In
+   an ECMAScript program, a Unicode escape sequence occurring within a comment
+   is never interpreted and therefore cannot contribute to termination of the
+   comment. Similarly, a Unicode escape sequence occurring within a string literal
+   in an ECMAScript program always contributes a character to the string value of
+   the literal and is never interpreted as a line terminator or as a quote mark
+   that might terminate the string literal.

+   Unicode escape sequence \u000A occurs within a string literal in a Java
+   program, it is likewise interpreted as a line terminator, which is not
+   allowed within a string literal-one must write \n instead of \u000A to
+   cause a line feed to be part of the string value of a string literal. In
+   an ECMAScript program, a Unicode escape sequence occurring within a comment
+   is never interpreted and therefore cannot contribute to termination of the
+   comment. Similarly, a Unicode escape sequence occurring within a string literal
+   in an ECMAScript program always contributes a character to the string value of
+   the literal and is never interpreted as a line terminator or as a quote mark
+   that might terminate the string literal.

+   File Name:          12.10-1.js
+   ECMA Section:       12.10 The with statement
+   Description:
+   WithStatement :
+   with ( Expression ) Statement
+
+   The with statement adds a computed object to the front of the scope chain
+   of the current execution context, then executes a statement with this
+   augmented scope chain, then restores the scope chain.
+
+   Semantics
+
+   The production WithStatement : with ( Expression ) Statement is evaluated
+   as follows:
+   1.  Evaluate Expression.
+   2.  Call GetValue(Result(1)).
+   3.  Call ToObject(Result(2)).
+   4.  Add Result(3) to the front of the scope chain.
+   5.  Evaluate Statement using the augmented scope chain from step 4.
+   6.  Remove Result(3) from the front of the scope chain.
+   7.  Return Result(5).
+
+   Discussion
+   Note that no matter how control leaves the embedded Statement, whether
+   normally or by some form of abrupt completion, the scope chain is always
+   restored to its former state.

+   the value of its AssignmentExpression when the VariableStatement is executed,
+   not when the variable is created.

+   Description:
+   The production IterationStatement : for ( LeftHandSideExpression in Expression )
+   Statement is evaluated as follows:
+
+   1.  Evaluate the Expression.
+   2.  Call GetValue(Result(1)).
+   3.  Call ToObject(Result(2)).
+   4.  Let C be "normal completion".
+   5.  Get the name of the next property of Result(3) that doesn't have the
+   DontEnum attribute. If there is no such property, go to step 14.
+   6.  Evaluate the LeftHandSideExpression (it may be evaluated repeatedly).
+   7.  Call PutValue(Result(6), Result(5)).  PutValue( V, W ):
+   1.  If Type(V) is not Reference, generate a runtime error.
+   2.  Call GetBase(V).
+   3.  If Result(2) is null, go to step 6.
+   4.  Call the [[Put]] method of Result(2), passing GetPropertyName(V)
+   for the property name and W for the value.
+   5.  Return.
+   6.  Call the [[Put]] method for the global object, passing
+   GetPropertyName(V) for the property name and W for the value.
+   7.  Return.
+   8.  Evaluate Statement.
+   9.  If Result(8) is a value completion, change C to be "normal completion
+   after value V" where V is the value carried by Result(8).
+   10. If Result(8) is a break completion, go to step 14.
+   11. If Result(8) is a continue completion, go to step 5.
+   12. If Result(8) is a return completion, return Result(8).
+   13. Go to step 5.
+   14. Return C.

+   Description:
+   The production IterationStatement : for ( LeftHandSideExpression in Expression )
+   Statement is evaluated as follows:
+
+   1.  Evaluate the Expression.
+   2.  Call GetValue(Result(1)).
+   3.  Call ToObject(Result(2)).
+   4.  Let C be "normal completion".
+   5.  Get the name of the next property of Result(3) that doesn't have the
+   DontEnum attribute. If there is no such property, go to step 14.
+   6.  Evaluate the LeftHandSideExpression ( it may be evaluated repeatedly).
+   7.  Call PutValue(Result(6), Result(5)).  PutValue( V, W ):
+   1.  If Type(V) is not Reference, generate a runtime error.
+   2.  Call GetBase(V).
+   3.  If Result(2) is null, go to step 6.
+   4.  Call the [[Put]] method of Result(2), passing GetPropertyName(V)
+   for the property name and W for the value.
+   5.  Return.
+   6.  Call the [[Put]] method for the global object, passing
+   GetPropertyName(V) for the property name and W for the value.
+   7.  Return.
+   8.  Evaluate Statement.
+   9.  If Result(8) is a value completion, change C to be "normal completion
+   after value V" where V is the value carried by Result(8).
+   10. If Result(8) is a break completion, go to step 14.
+   11. If Result(8) is a continue completion, go to step 5.
+   12. If Result(8) is a return completion, return Result(8).
+   13. Go to step 5.
+   14. Return C.

+   15.5.2.2 new String()
+
+   Description:	When String is called as part of a new expression, it
+   is a constructor; it initializes the newly constructed
+   object.
+
+   - The prototype property of the newly constructed
+   object is set to the original String prototype object,
+   the one that is the intial value of String.prototype
+   - The internal [[Class]] property of the object is "String"
+   - The value of the object is ToString(value).
+   - If no value is specified, its value is the empty string.

+   ECMA Section:       15.5.4.10 String.prototype.substring( start, end )
+   Description:
+
+   15.5.4.10 String.prototype.substring(start, end)
+
+   Returns a substring of the result of converting this object to a string,
+   starting from character position start and running to character position
+   end of the string. The result is a string value, not a String object.
+
+   If either argument is NaN or negative, it is replaced with zero; if either
+   argument is larger than the length of the string, it is replaced with the
+   length of the string.
+
+   If start is larger than end, they are swapped.
+
+   When the substring method is called with two arguments start and end, the
+   following steps are taken:
+
+   1.  Call ToString, giving it the this value as its argument.
+   2.  Call ToInteger(start).
+   3.  Call ToInteger (end).
+   4.  Compute the number of characters in Result(1).
+   5.  Compute min(max(Result(2), 0), Result(4)).
+   6.  Compute min(max(Result(3), 0), Result(4)).
+   7.  Compute min(Result(5), Result(6)).
+   8.  Compute max(Result(5), Result(6)).
+   9.  Return a string whose length is the difference between Result(8) and
+   Result(7), containing characters from Result(1), namely the characters
+   with indices Result(7) through Result(8)1, in ascending order.
+
+   Note that the substring function is intentionally generic; it does not require
+   that its this value be a String object. Therefore it can be transferred to other
+   kinds of objects for use as a method.

+   File Name:          15.5.4.11-2.js
+   ECMA Section:       15.5.4.11 String.prototype.toLowerCase()
+   Description:
+
+   Returns a string equal in length to the length of the result of converting
+   this object to a string. The result is a string value, not a String object.
+
+   Every character of the result is equal to the corresponding character of the
+   string, unless that character has a Unicode 2.0 uppercase equivalent, in which
+   case the uppercase equivalent is used instead. (The canonical Unicode 2.0 case
+   mapping shall be used, which does not depend on implementation or locale.)
+
+   Note that the toLowerCase function is intentionally generic; it does not require
+   that its this value be a String object. Therefore it can be transferred to other
+   kinds of objects for use as a method.

+   Description:
+
+   Returns a string equal in length to the length of the result of converting
+   this object to a string. The result is a string value, not a String object.
+
+   Every character of the result is equal to the corresponding character of the
+   string, unless that character has a Unicode 2.0 uppercase equivalent, in which
+   case the uppercase equivalent is used instead. (The canonical Unicode 2.0 case
+   mapping shall be used, which does not depend on implementation or locale.)
+
+   Note that the toLowerCase function is intentionally generic; it does not require
+   that its this value be a String object. Therefore it can be transferred to other
+   kinds of objects for use as a method.

+   File Name:          15.5.4.12-3.js
+   ECMA Section:       15.5.4.12 String.prototype.toUpperCase()
+   Description:
+
+   Returns a string equal in length to the length of the result of converting
+   this object to a string. The result is a string value, not a String object.
+
+   Every character of the result is equal to the corresponding character of the
+   string, unless that character has a Unicode 2.0 uppercase equivalent, in which
+   case the uppercase equivalent is used instead. (The canonical Unicode 2.0 case
+   mapping shall be used, which does not depend on implementation or locale.)
+
+   Note that the toUpperCase function is intentionally generic; it does not require
+   that its this value be a String object. Therefore it can be transferred to other
+   kinds of objects for use as a method.

+   File Name:          15.5.4.12-1.js
+   ECMA Section:       15.5.4.12 String.prototype.toUpperCase()
+   Description:
+
+   Returns a string equal in length to the length of the result of converting
+   this object to a string. The result is a string value, not a String object.
+
+   Every character of the result is equal to the corresponding character of the
+   string, unless that character has a Unicode 2.0 uppercase equivalent, in which
+   case the uppercase equivalent is used instead. (The canonical Unicode 2.0 case
+   mapping shall be used, which does not depend on implementation or locale.)
+
+   Note that the toUpperCase function is intentionally generic; it does not require
+   that its this value be a String object. Therefore it can be transferred to other
+   kinds of objects for use as a method.

+   File Name:          15.5.4.4-3.js
+   ECMA Section:       15.5.4.4 String.prototype.charAt(pos)
+   Description:        Returns a string containing the character at position
+   pos in the string.  If there is no character at that
+   string, the result is the empty string.  The result is
+   a string value, not a String object.
+
+   When the charAt method is called with one argument,
+   pos, the following steps are taken:
+   1. Call ToString, with this value as its argument
+   2. Call ToInteger pos
+   3. Compute the number of characters  in Result(1)
+   4. If Result(2) is less than 0 is or not less than
+   Result(3), return the empty string
+   5. Return a string of length 1 containing one character
+   from result (1), the character at position Result(2).
+
+   Note that the charAt function is intentionally generic;
+   it does not require that its this value be a String
+   object.  Therefore it can be transferred to other kinds
+   of objects for use as a method.
+
+   This tests assiging charAt to a user-defined function.

+   3. Compute the number of characters in result(1).
+   4. If Result(2) is less than 0 or is not less than

+   File Name:          15.5.4.5.1.js
+   ECMA Section:       15.5.4.5 String.prototype.charCodeAt(pos)
+   Description:        Returns a number (a nonnegative integer less than 2^16)
+   representing the Unicode encoding of the character at
+   position pos in this string.  If there is no character
+   at that position, the number is NaN.
+
+   When the charCodeAt method is called with one argument
+   pos, the following steps are taken:
+   1. Call ToString, giving it the theis value as its
+   argument
+   2. Call ToInteger(pos)
+   3. Compute the number of characters in result(1).
+   4. If Result(2) is less than 0 or is not less than
+   Result(3), return NaN.
+   5. Return a value of Number type, of positive sign, whose
+   magnitude is the Unicode encoding of one character
+   from result 1, namely the characer at position Result
+   (2), where the first character in Result(1) is
+   considered to be at position 0.
+
+   Note that the charCodeAt function is intentionally
+   generic; it does not require that its this value be a
+   String object.  Therefore it can be transferred to other
+   kinds of objects for use as a method.

+   ECMA Section:       15.5.4.7 String.prototype.lastIndexOf( searchString, pos)
+   Description:
+
+   If the given searchString appears as a substring of the result of
+   converting this object to a string, at one or more positions that are
+   at or to the left of the specified position, then the index of the
+   rightmost such position is returned; otherwise -1 is returned. If position
+   is undefined or not supplied, the length of this string value is assumed,
+   so as to search all of the string.
+
+   When the lastIndexOf method is called with two arguments searchString and
+   position, the following steps are taken:
+
+   1.Call ToString, giving it the this value as its argument.
+   2.Call ToString(searchString).
+   3.Call ToNumber(position). (If position is undefined or not supplied, this step produces the value NaN).
+   4.If Result(3) is NaN, use +; otherwise, call ToInteger(Result(3)).
+   5.Compute the number of characters in Result(1).
+   6.Compute min(max(Result(4), 0), Result(5)).
+   7.Compute the number of characters in the string that is Result(2).
+   8.Compute the largest possible integer k not larger than Result(6) such that k+Result(7) is not greater
+   than Result(5), and for all nonnegative integers j less than Result(7), the character at position k+j of
+   Result(1) is the same as the character at position j of Result(2); but if there is no such integer k, then
+   compute the value -1.
+
+   1.Return Result(8).
+
+   Note that the lastIndexOf function is intentionally generic; it does not require that its this value be a
+   String object. Therefore it can be transferred to other kinds of objects for use as a method.

+   Description:
+
+   Returns an Array object into which substrings of the result of converting
+   this object to a string have been stored. The substrings are determined by
+   searching from left to right for occurrences of the given separator; these
+   occurrences are not part of any substring in the returned array, but serve
+   to divide up this string value. The separator may be a string of any length.
+
+   As a special case, if the separator is the empty string, the string is split
+   up into individual characters; the length of the result array equals the
+   length of the string, and each substring contains one character.
+
+   If the separator is not supplied, then the result array contains just one
+   string, which is the string.

+   File Name:          15.5.4.8-2.js
+   ECMA Section:       15.5.4.8 String.prototype.split( separator )
+   Description:
+
+   Returns an Array object into which substrings of the result of converting
+   this object to a string have been stored. The substrings are determined by
+   searching from left to right for occurrences of the given separator; these
+   occurrences are not part of any substring in the returned array, but serve
+   to divide up this string value. The separator may be a string of any length.
+
+   As a special case, if the separator is the empty string, the string is split
+   up into individual characters; the length of the result array equals the
+   length of the string, and each substring contains one character.
+
+   If the separator is not supplied, then the result array contains just one
+   string, which is the string.
+
+   When the split method is called with one argument separator, the following steps are taken:
+
+   1.   Call ToString, giving it the this value as its argument.
+   2.   Create a new Array object of length 0 and call it A.
+   3.   If separator is not supplied, call the [[Put]] method of A with 0 and
+   Result(1) as arguments, and then return A.
+   4.   Call ToString(separator).
+   5.   Compute the number of characters in Result(1).
+   6.   Compute the number of characters in the string that is Result(4).
+   7.   Let p be 0.
+   8.   If Result(6) is zero (the separator string is empty), go to step 17.
+   9.   Compute the smallest possible integer k not smaller than p such that
+   k+Result(6) is not greater than Result(5), and for all nonnegative
+   integers j less than Result(6), the character at position k+j of
+   Result(1) is the same as the character at position j of Result(2);
+   but if there is no such integer k, then go to step 14.
+   10.   Compute a string value equal to the substring of Result(1), consisting
+   of the characters at positions p through k1, inclusive.
+   11.   Call the [[Put]] method of A with A.length and Result(10) as arguments.
+   12.   Let p be k+Result(6).
+   13.   Go to step 9.
+   14.   Compute a string value equal to the substring of Result(1), consisting
+   of the characters from position p to the end of Result(1).
+   15.   Call the [[Put]] method of A with A.length and Result(14) as arguments.
+   16.   Return A.
+   17.   If p equals Result(5), return A.
+   18.   Compute a string value equal to the substring of Result(1), consisting of
+   the single character at position p.
+   19.   Call the [[Put]] method of A with A.length and Result(18) as arguments.
+   20.   Increase p by 1.
+   21.   Go to step 17.
+
+   Note that the split function is intentionally generic; it does not require that its this value be a String
+   object. Therefore it can be transferred to other kinds of objects for use as a method.

+   18.   Compute a string value equal to the substring of Result(1), consisting of
+   the single character at position p.
+   19.   Call the [[Put]] method of A with A.length and Result(18) as arguments.

+   File Name:          9.5-2.js
+   ECMA Section:       9.5  Type Conversion:  ToInt32
+   Description:        rules for converting an argument to a signed 32 bit integer
+
+   this test uses << 0 to convert the argument to a 32bit
+   integer.
+
+   The operator ToInt32 converts its argument to one of 2^32
+   integer values in the range -2^31 through 2^31 inclusive.
+   This operator functions as follows:
+
+   1 call ToNumber on argument
+   2 if result is NaN, 0, -0, return 0
+   3 compute (sign (result(1)) * floor(abs(result 1)))
+   4 compute result(3) modulo 2^32:
+   5 if result(4) is greater than or equal to 2^31, return
+   result(5)-2^32.  otherwise, return result(5)
+
+   special cases:
+   -0          returns 0
+   Infinity    returns 0
+   -Infinity   returns 0
+   ToInt32(ToUint32(x)) == ToInt32(x) for all values of x
+   Numbers greater than 2^31 (see step 5 above)
+   (note http://bugzilla.mozilla.org/show_bug.cgi?id=120083)

+   File Name:          9.8.1.js
+   ECMA Section:       9.8.1 ToString Applied to the Number Type
+   Description:        The operator ToString convers a number m to string
+   as follows:
+
+   1.  if m is NaN, return the string "NaN"
+   2.  if m is +0 or -0, return the string "0"
+   3.  if m is less than zero, return the string
+   concatenation of the string "-" and ToString(-m).
+   4.  If m is Infinity, return the string "Infinity".
+   5.  Otherwise, let n, k, and s be integers such that
+   k >= 1, 10k1 <= s < 10k, the number value for s10nk
+   is m, and k is as small as possible. Note that k is
+   the number of digits in the decimal representation
+   of s, that s is not divisible by 10, and that the
+   least significant digit of s is not necessarily
+   uniquely determined by these criteria.
+   6.  If k <= n <= 21, return the string consisting of the
+   k digits of the decimal representation of s (in order,
+   with no leading zeroes), followed by n-k occurences
+   of the character '0'.
+   7.  If 0 < n <= 21, return the string consisting of the
+   most significant n digits of the decimal
+   representation of s, followed by a decimal point
+   '.', followed by the remaining kn digits of the
+   decimal representation of s.
+   8.  If 6 < n <= 0, return the string consisting of the
+   character '0', followed by a decimal point '.',
+   followed by n occurences of the character '0',
+   followed by the k digits of the decimal
+   representation of s.
+   9.  Otherwise, if k = 1, return the string consisting
+   of the single digit of s, followed by lowercase
+   character 'e', followed by a plus sign '+' or minus
+   sign '' according to whether n1 is positive or
+   negative, followed by the decimal representation
+   of the integer abs(n1) (with no leading zeros).
+   10.  Return the string consisting of the most significant
+   digit of the decimal representation of s, followed
+   by a decimal point '.', followed by the remaining k1
+   digits of the decimal representation of s, followed
+   by the lowercase character 'e', followed by a plus
+   sign '+' or minus sign '' according to whether n1 is
+   positive or negative, followed by the decimal
+   representation of the integer abs(n1) (with no
+   leading zeros).
+
+   Note that if x is any number value other than 0, then
+   ToNumber(ToString(x)) is exactly the same number value as x.
+
+   As noted, the least significant digit of s is not always
+   uniquely determined by the requirements listed in step 5.
+   The following specification for step 5 was considered, but
+   not adopted:

+   integers. The leftmost character (if any) is at position 0, the next
+   character (if any) at position 1, and so on. The length of a string is the
+   number of distinct positions within it. The empty string has length zero
+   and therefore contains no characters.

+   File Name:          10.1.4-9.js
+   ECMA Section:       10.1.4 Scope Chain and Identifier Resolution
+   Description:
+   Every execution context has associated with it a scope chain. This is
+   logically a list of objects that are searched when binding an Identifier.
+   When control enters an execution context, the scope chain is created and
+   is populated with an initial set of objects, depending on the type of
+   code. When control leaves the execution context, the scope chain is
+   destroyed.
+
+   During execution, the scope chain of the execution context is affected
+   only by WithStatement. When execution enters a with block, the object
+   specified in the with statement is added to the front of the scope chain.
+   When execution leaves a with block, whether normally or via a break or
+   continue statement, the object is removed from the scope chain. The object
+   being removed will always be the first object in the scope chain.
+
+   During execution, the syntactic production PrimaryExpression : Identifier
+   is evaluated using the following algorithm:
+
+   1.  Get the next object in the scope chain. If there isn't one, go to step 5.
+   2.  Call the [[HasProperty]] method of Result(l), passing the Identifier as
+   the property.
+   3.  If Result(2) is true, return a value of type Reference whose base object
+   is Result(l) and whose property name is the Identifier.
+   4.  Go to step 1.
+   5.  Return a value of type Reference whose base object is null and whose
+   property name is the Identifier.
+   The result of binding an identifier is always a value of type Reference with
+   its member name component equal to the identifier string.

+   File Name:          10.1.6
+   ECMA Section:       Activation Object
+   Description:
+
+   If the function object being invoked has an arguments property, let x be
+   the value of that property; the activation object is also given an internal
+   property [[OldArguments]] whose initial value is x; otherwise, an arguments
+   property is created for the function object but the activation object is
+   not given an [[OldArguments]] property. Next, arguments object described
+   below (the same one stored in the arguments property of the activation
+   object) is used as the new value of the arguments property of the function
+   object. This new value is installed even if the arguments property already
+   exists and has the ReadOnly attribute (as it will for native Function
+   objects). (These actions are taken to provide compatibility with a form of

+   File Name:          10.1.8
+   ECMA Section:       Arguments Object
+   Description:
+
+   When control enters an execution context for declared function code,
+   anonymous code, or implementation-supplied code, an arguments object is
+   created and initialized as follows:
+
+   The [[Prototype]] of the arguments object is to the original Object
+   prototype object, the one that is the initial value of Object.prototype
+   (section 15.2.3.1).
+
+   A property is created with name callee and property attributes {DontEnum}.
+   The initial value of this property is the function object being executed.
+   This allows anonymous functions to be recursive.
+
+   A property is created with name length and property attributes {DontEnum}.
+   The initial value of this property is the number of actual parameter values
+   supplied by the caller.
+
+   For each non-negative integer, iarg, less than the value of the length
+   property, a property is created with name ToString(iarg) and property
+   attributes { DontEnum }. The initial value of this property is the value
+   of the corresponding actual parameter supplied by the caller. The first
+   actual parameter value corresponds to iarg = 0, the second to iarg = 1 and
+   so on. In the case when iarg is less than the number of formal parameters
+   for the function object, this property shares its value with the
+   corresponding property of the activation object. This means that changing
+   this property changes the corresponding property of the activation object
+   and vice versa. The value sharing mechanism depends on the implementation.

+   (Note that this step differs from step 3 in the algorithm for comparison

+   2. Call ToInteger pos
+   3. Compute the number of characters  in Result(1)

+
+   Note that the charAt function is intentionally generic;

+   so as to search all of the string.
+
+   When the lastIndexOf method is called with two arguments searchString and
+   position, the following steps are taken:
+
+   1.Call ToString, giving it the this value as its argument.
+   2.Call ToString(searchString).
+   3.Call ToNumber(position). (If position is undefined or not supplied, this step produces the value NaN).
+   4.If Result(3) is NaN, use +; otherwise, call ToInteger(Result(3)).
