Replying to [comment:6 mkosters]:
> In the new patch you can check if an element is a zero divisor, do a
base change and check if an element is nilpotent (it also fixes the power
function if there is no one etc).

one?
I've uploaded a combined patch. A few remarks about documentation:
* Please be more precise: Is your inverse a left or right inverse? Same
question about zero divisors, etc.
* In the first line of a docstring, put the verb in the imperative (not
extremely important, but more direct and grammatically better than
"Returns blabla" without a subject).
* Put a blank line between the double colon and the doctests (used for
html generation of documentation).
