Currently mod and Mod are the same function. I think that this

There seem to be plenty of ways to construct elements of Z/nZ
quickly. I would say that the only thing in question is what the
behavior of a.mod(b) should be: the same as the global function mod,
or the same as the method __mod__ that defines the % operator.
Yep. Note that mod is not an element of Integer, but of Ring Element,
and takes an ideal in general (returning a representative in that
ideal). Changing this to return an element of the quotient ring
instead could be very backwards incompatible.
