Clojure hosted on Chez Scheme (same as Racket). So cool. I tried building a standalone executable for the Chess game in my Clojure book using "jolt build -m chess-game.cli -o chess_jolt" and it simply worked great.

I tried again with a datomic demo and it needed the source code to the open source version of datomic, so I need to do some work on that.
