A natural spot is where I introduced the trick that forces the
replacement of the lazy import by the object itself: in
CategoryWithAxiom.__classget__.
But then the trick is no more complicated than the assertion test, and
the trick by itself solves the problem now. So honestly I don't see
why bother :-)
