Hi Barak, In a sense, defaulting in Haskell *is* a mechanism to address common innocuous cases in an ad-hoc way (although it still has a relatively simple and easy to understand semantics). If you'd like something even more ad-hoc, take a look at Ruby or JavaScript: http://www.youtube.com/watch?v=kXEgk1Hdze0 Roman _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
