Hmm, adding:

seems to bring a lot of positives and by quick inspection most of them seem
like same classes. I will try to find some time to debug this more. But
glancing over the the dumps, I see many of them just have different name
spaces. Do we even attempt to merge namespace_decl? How types from same
namespaces in different units are supposed to match?
