Clojure

Clojure is a LISP-dialect programming language that runs on the Java Virtual Machine and the .NET CLR. The language is dynamic, has first-class functions, macros immutable values, concurrency and can access all the libraries of the host platform. Clojure development started in 2007 by Rich Hickey, and the first stable version (1.0.0) was released on May 4, 2009.
