== Description

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?

== Features

* Implements non-local exits for methods
* Nestable
* Named and stack-based exit points, go exactly where you need to be
* Full exception handling support through raise!, rescue! and ensure!
* Ignores pesky ensure, rescue and require blocks for when you really, really
need to return

== Problems

* Not enough use of continuations

== Synopsis

require 'return_bang/everywhere'

def some_method
deeply_nested
# never reached
end

def deeply_nested
return!
end

return_here do
some_method
end
# resumes here
