So execution speed, fair enough.

FWIW, I've been staying away from Clojure because of the JVM. A lot of us are wearing the scars of the JVM battles!

If you need performance and want to avoid the jvm, there are also lisps like Chez Scheme and various Common Lisp implementations (sbcl, in particular, can produce really well-tuned numerical code).

... which is why Racket-on-Chez[0] is a really exciting development.

"Keep in mind that the original goal is not to have a faster Racket, but a better-implemented Racket with acceptable performance."
