module to manipulate upper scopes


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
 * Return values immediately to an upper level with "unwind", and know
   which context was in use then with "want_at"
