By "tried", do you mean you built a DLL out of a non-trivial Python
extension and the Python interpreter on Windows loaded it successfully?

I'm a LLVM/Clang committer, so I know how mature it is. What I'm
questioning is current Clang's ability to generate Windows executables that
conform to the MSVC ABI. It's not exactly my domain of expertise, but last
I heard this isn't yet prime-time ready. Maybe you have more up-to-date
information - this is what I'm asking.
