Replying to [comment:11 vdelecroix]:
> I do not care so much as it is specified in the documentation. But a
number field is always the quotient field of its maximal order... Do you
think we should care?
The problem is that a `gcd()` is not always defined for maximal orders in
number fields (if the class number is not 1). So we cannot simply use the
fraction field implementation. And for consistency, I don't want to treat
the class-number=1 case differently.
