A few years back, Jython creator Jim Hugunin decided the best way to prove the theory that the CLI was not an ideal environment for scripting languages was by actually implementing one capable of running on it. He chose Python as the test language, and set about building a .NET compatible version. The result? His version, dubbed IronPython, ran far more efficiently than he’d ever imagined. In fact, in many cases IronPython now runs faster than the C-based version!
After several years of ongoing work, version 1.0 has been released.

You wrote CLI, I think it’s CLR you wanted to write.
Nothing more powerful than a command line interface :)
