Comment(by SimonKing):
It was suggested on sage-devel to have both: By making `x` an optional
argument, `Q.lift()` could return the lifting map (following the old rules
of sage.rings.quotient_ring), and `Q.lift(x)` could return a lift of x
(following the old rules of the category framework).
I think I will go for that solution.
Unfortunately, I was not told yet whether I shall duplicate the code, or
move it...
