Fair enough, you seem to be well informed so we can just agree to disagree.

And thanks for mentioning metalua, I had never heard of it! I know some lua but I'm far from being an expert, nor have I used it in anything larger than a few hundred lines.

I'm not the biggest fan of Common Lisp either, I too prefer the Scheme side of things though I don't think we haven't reached the golden standard yet (in my mind it would be a Clojure-like functional Lisp with first class support for actors, that compiles to native code)
