This is only a lookup in a map that we created. But this only works for tag types, not for namespaces. My approach now uses `Type::GetTypeScopeAndBasename` to split the undecorated name. At first, it assumes everything is a namespace and then walks backwards to find parent types.

I'm not sure what the best way to test this is.
