Comment (by SimonKing):
Replying to [comment:19 nbruin]:
> But it does mean that if `B` here were to be identical to `A`, then the
first example would permanently poison the sage session with nonsense.
And that's why I think it is a good idea that ''all'' given arguments,
including the category, are taken into the cache key of the factory. That
way, it won't matter if you put a non-field into the category of fields,
because you are still able to create a "sane" version of the same ring.
> So I'd think `IntegerModRing(16,category=Fields())` should produce an
error.
I don't think so. And in any case, it should be on a different ticket.
