Hello - I was just looking around and happened upon the following two sources:

http://www.ruby-talk.org/cgi-bin/scat.rb/ruby/ruby-talk/102817

http://rubygarden.org/ruby/ruby?action=browse&id=InterfaceContracts&revision=26


Just out of curiosity, I'm wondering whether there's any further/current 
information/discussion(s) regarding the implemenation of Interfaces w/ ruby.

Thanks!
