We don't really have a choice, the C API does not offer all the features we need and we also need to follow the new LLVM changes internally. Hopefully, the LLVM team is always helping us :-)

It will very likely collide at runtime... until we un-export all symbols (but the C extension ones) from the link phase, which should happen in theory for our next release, 0.6.
