Exciting idea, I love Clojure, but every time I tried Clojure, I found myself butting heads with the Java ecosystem, and I always wished it had its own ecosystem and interpreter/compiler. I will caveat that that's just because I've never spent long in the Java ecosystem, so it's not a criticism of the current Clojure + Java ecosystem, more my own lack of experience.
