return_bang version 1.0 has been released!

• docs.seattlerb.org/return_bang

• github.com/drbrain/return_bang

return_bang implements non-local exits from methods. 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

• Ignores pesky ensure blocks for when you really, really need to return

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
