Don't want to side track too much, but yes, given that it is on the JVM and can bind to Java libs it's not too risky for production, that being said Clojure is slower than Java on the JVM so I would not use it where performance is critical (it's not that slow though). But for the majority of use cases it works just find. By no means is it experimental Clojure has the reputation of being the practical Lisp given it's ability to use the wealth of Java libs.
