I always had that opinion about that feature too. It's present in quite a few languages. I think people like to point out that they can do things that you can't in other languages and end up going ridiculous paths. As if the real power of a programming language could be inferred from it's syntax. Don't get me wrong, I like coffee script and I find the tool linked on this thread quite useful, but come on... rewriting all the 'ifs' as 'unless' jut because you can looks pointless and silly to me. Just my opinion.
