Vala --- a c# style modern language that can be compiled to c

I just learned that there is a programming language that is both efficient and relatively easy to program: vala. It can be compiled to c, then to the assembly language by a c compiler.

Compared to C++, vala's advantage is that:

Vala has no header file.

Vala has garbage collection.

Nice and clear C# style grammar and no strange C++ operator like :: , >> , << , ->

Easy collaboration with C.

However, it is not so famous and widely used. I will try to learn more about it in the future to see its potential -- maybe one day, it can replace c++ in the game industry?
