return_bang implements non-local exits for methods. As a bonus, you
also get
exception handling that ignores standard Ruby’s inflexible begin;
rescue;
ensure; end syntax.
Use return_bang to exit back to a processing loop from deeply nested
code, or
just to confound your enemies and your friends! What could possibly
go
wrong?
=== 1.1 / 2012-04-01
- Minor enhancements
- Added raise! to raise exceptions
- Added rescue! to rescue exceptions raised
- Added ensure! to always execute a block of code to perform cleanup

Maybe next year I can add more continuations to return_bang
