Comment (by vdelecroix):
Replying to [comment:28 cheuberg]:
> This is now refactored as a try/expect block; polynomial exponents are
now disallowed.
Thanks.
> I am not completely comfortable with the long block wrapped within
`try`/`expect` because I am not sure that we catch the correct
`TypeError`. What do you think about that?
Right. It is better to avoid long `try/except`. One possibility is
{{{
try:
nn = pyobject_to_long(exp)
except TypeError:
# rational code
else:
# integer code
}}}
