I know a lot of people are going to poo poo on this as "not a lisp" but I think it makes lisps more approachable for a python programmer who is not used to them. I used experimented with Hy a few years ago and I felt that it made it easier to write recursive functions (even if python doesn't have tail call optimization). Being able to bind multiple values to multiple variables was nice, and I believe I could…

This terminal cracked me up: http://try-hy.appspot.com/

Has anybody used this in a production application? I use Clojure at work and want to use Lisp in personal projects but it seems that it would be much easier to have a Python web app instead of a JVM based one as there are shared hosts that offer Python.
