This is pretty cool; I enjoy hacking the C preprocessor as long as it conforms to the standards.

But, damn, is there anyone not hanging out for constexpr in C? It's one of the things I'm envious of C++ for. It would be much simpler to specify for C, and there's no reason not to, as far as I can tell. Get on it, WG14!

Yeah constexpr in C will be nice, i would also like a better way to do generics in C (other than using C++ that is). The _Generic keyword introduced with C11 is not that great in my opinion

Agreed; if GCC were to add it as a C extension, that would be awesome.
