Ah. I guess I'll want that once I have a working toolchain.

It's going to be a compiler project. The usual setup: C++ for 
scanner/parser/AST/diagnostics, LLVM for the backend. Self-hosting 
comiler may happen later, and will continue to use LLVM.
So my plans for using LLVM are long-term, and at least mid-term for Clang.

I've been planning to switch to a new release whenever it's out.
What are the advantages of following trunk?
