Comment (by SimonKing):
Replying to [comment:21 SimonKing]:
> - Do not allow to put in a "category" argument. But then, we might want
to learn the rationale of introducing the argument in the first place.
After all, if the modulus of integer mod ring R is a prime number, then
asking `R in Fields()` will return true. So, if one knows during creation
of the ring that the modulus is prime, one might use `GF(p)` instead of
`IntegerModRing(p,category=Fields())`.
How embarrassing!
I just used `git blame` to find out who introduced the use of a "category"
argument for integer mod rings---and found that it was '''I''', namely in
#9138.
I hope #9138 gives a rationale...
