README

This module lets you defer actions at run-time that will take place
when the control flow returns into an upper scope. 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".
