simple forwards speced and impmtd

I have been searching for forwarding libraries for JS in vain (I avoid use of the term delegation here on purpose to avoid any polemic on it).
So I took an hour or two on implementing but the most basic functionality of my Forwarder19 library for Ruby https://github.com/RobertDober/Forwarder19, to check if my Javascript Hero (correction Coffeescript Hero) would be interested.
Cheers
Robert

P.S. I am quite sure about the guidelines for contributing, maybe a little bit confused about the last.
