Hi Manuel (and company),

I'm really behind on code review, so maybe this was already discussed... but why does it make sense to take this into clang mainline?

I thought we previously discussed that enabling people to do pattern matching on ast's by *REBUILDING THE COMPILER* is not a particularly interesting thing to do, and there are ways to do it already with the libclang API.

What problem is this solving and why should it be in mainline?
