Clojure

Besides the JVM, Clojure also targets CLR, the Clojure Language Runtime.

The CLR is a native implementation of Clojure on Microsoft's .Net Framework, programmed in C# and using the Dynamic Language Runtime (DLR).

Before being such a big deal on the development market, Clojure started out as a simple experiment, just another Lisp dialect.

It then evolved into a mammoth must-have tool after it started being used to compiled directly to JVM bytecode, while still remaining open for editing and changes in the code in real-time.

This dynamic compilation features makes it much more usable in production environments, where Java can sometimes be annoying to work with.
