Comment (by nthiery):
Hi Travis!
Thanks for the improvement! I made one further step, in particular to
avoid trapping too many exceptions; typical situation: a parent L that
implements
unranking as L[i] and raises an "out of bound" value error.
I am still unhappy about the `unrank(ZZ,i)` returning something completely
wrong (Integer Ring). In case a parent is iterable, I wonder if I would
not prefer to prefer the Iterable strategy, and only use __getitem__ if
everything else has failed.
Cheers,
Nicolas
