That just makes me frustrated. I know Lisp is the urlang from which all dynamic languages come from, I know that it's mutable into your personal tastes, but can we please standardize on a previously used set of forms? I respect and encourage people's desires to make a toylang, but if you want to promote it into "language for other people", things like portability become more important. I'm a common lisp guy, so obviously those are the best. ;-) But more importantly, I can run Common Lisp from before I was born. And I love that longjevity of my code and other people's code.
