I'm not a big fan of a lot of non-standard additions to Ruby. For example, all the #try, or #returning, or even your #andand. I don't consider any of those to have enough intrinsic value to be worth the risk of collisions with someone else's subtly different implementation. #andand is soooooooo "raganwald." The Homoiconic Way is to use rewrite: #try, #returning, and #andand are all removed from your code and never conflict with other people's implementations ;-)
