I'd love to see a comparison with Clojure, anyone know of such a thing yet?
- Clojure vs LFE
- JVM vs BEAM
- Lisp-1 vs Lisp-2
Etc, if you are interested only in the syntax differences, there is not much difference there (there are obviously some though!). I think generally speaking Erlang has fewer libraries than Java so that is a big difference in my opinion.
