Nice. Did you know about our Lua/Clang binding?
Different features/motivations of course; we've been concentrating on using it for the JIT compilation of C++ code, and recently I've been playing with the C-binding to LLVM via LuaJIT's FFI. An FFI-to-clang-c is in the works.
Perhaps there's an opportunity to merge efforts?
