Why are sqrtn(x,p) and x^(1/p) less obvious ?

What's wrong with sqrtn(x,p) ?

Okay, true.  I guess I was thinking too much as a programmer instead of
a mathematician.  By the way, these functions don't work for finite
field POLMODs, so it's not *that* obvious :-)

It doesn't seem to be possible currently (only x.p and x.pol work).
I'll add x.mod to the allowed member functions

Maybe you could also add lift(x) to make things more analogous to POLMODs.
