Replying to [comment:6 ppurka]:
> With the `//` operator you are actually getting Sage integers, whereas I
was getting Sage rationals with the `/` operator. That explains why the
coercion to `Integers` was taking so much time.
Yes, I noticed that, but I thought you were using rationals on purpose.
What I would like to understand is where the ~2 µs of overhead in the
version using `self(ZZ.random_element(0, self.__order-1))` come from...
