Vala

Vala is an object-oriented programming language with a self-hosting compiler that generates C code and uses the GObject system. Vala is syntactically similar to C# and and rather than being compiled directly to assembly or to another intermediate language, Vala is source-to-source compiled to C, which is then compiled with a platform’s standard C compiler, such as GCC. You can also create VAPI files which are basically native C (not C++) functions you can import to Vala code (I will show an example later).
