Fantom
Fantom is a modern general purpose, strongly typed programming language similar to Java and C# with a succinct type model and rich libraries. Being a typical hybrid language it integrates object-oriented and functional programming features with a strong focus on simplicity and efficency. Includes a module system for platform independent applications as well as handy build, test, and documentation tools. Compiles to JVM-bytecode, .NET CLR code, or JavaScript.
