1 This module lets you defer actions at run-time that will take place when the
2 control flow returns into an upper scope. Currently, you can:
4 * hook an upper scope end with "reap"
5 * localize variables, array/hash values or deletions of elements in
6 higher contexts with respectively "localize", "localize_elem" and
8 * return values immediately to an upper level with "unwind", and know
9 which context was in use then with "want_at"
