Clojure

Clojure (pronounced like "closure"[3]) is a dialect of the Lisp programming language created by Rich Hickey. Clojure is a functional general-purpose language, and runs on the Java Virtual Machine (JVM), Common Language Runtime, and JavaScript engines. Like other Lisps, Clojure treats code as data and has a sophisticated macro system. http://en.wikipedia.org/wiki/Clojure
