It’s a new language with C#-like syntax with a compiler that generates C code. Could be interesting. Although, generally speaking, code generators suck, you shouldn’t have to deal with the generated code at all in this case. The code is written in Vala, which is compiled to native code, but if you create a library it will have (or generate?) an API that is compatible with C.
I am going to have to try this some time (because, you know, I have lots of free time to spend on playing around with obscure programming languages, oh wait, I don’t ;-) So, has anyone else tried this?
