I feel there could be solutions. Either module.__getattribute__ (which,
IIRC, was implemented recently), or just using a proxy/wrapper class around
non-Union[class, function] objects. Those are rare, though, in imported
modules. And I don't think this library will see much use without the
subjects being imported first - at least I know I do my refactors on a
per-file basis. And if you can't, you might want to split your files first.
