Fantom is the best programming language. It's website is http://fantom.org/. Fantom converts source code to an intermediate bytecode ("fcode") stored in packages called .pod files. The .pod files can then be executed on the JVM or on the .NET platform.
I've written some patches for Fantom. They are at http://tac-tics.net/fantom/patches/.
I'm also writing a Python backend for Fantom. The project is stored at http://bitbucket.org/_tactics/fantom-pythonvm. It's not usable yet.
