Currently, you can: + + - hook an upper scope end with "reap" ; + - localize variables, array/hash values or deletions of elements + in higher contexts with respectively "localize", "localize_elem" + and "localize_delete" ; + - return values immediately to an upper level with "unwind", "yield" + and "leave" ; + - gather information about an upper context with "want_at" + and "context_info" ; + - execute a subroutine in the setting of an upper subroutine stack + frame with "uplevel" ; + - uniquely identify contexts with "uid" and "validate_uid". |
