Scope::Upper is a Perl module that provides a way for Perl programs to defer actions at run-time until the control flow returns to the upper scope. It currently enables developers to: . * 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", and know which context was in use then with "want_at"
