> Really, by the time you've established that `Z/nZ` is an integral
domain, you can refine it to field anyway (which is an integral domain).
Sure, in the case of Z/nZ this is true. However, I tried to implement this
on the level of categories, and I don't think that `IntegralDomains()`
should try to refine to `Fields()`. One could of course implement this in
`IntegerModRing` but I believe it is cleaner like this.
