Comment (by SimonKing):
BTW: This explains why the code was more or less working, in spite of the
recursion. Namely, apparently the import or recursion error resulted in
`hasattr(nested_cls, "_base_category_class_and_axiom")` returning False
(without error!), and from there, things worked, since then the lazy
attribute was overridden with its correct value by the `classget`.
Now, we override the lazy attribute with its correct value by the
`classget` right away, without spending time on waiting for an error to
happen...
