Honestly, I'm not so sure, Clang is modern and has been designed with
extensibility and performance from day 0. I think it will be quite hard
to compete with it and I wonder why are you willing to spend that much
effort instead of contributing to Clang. If you said that about GCC,
I could agree, but with Clang, at least for me, is harder to sell that
argument.
