Comment:
Hi,
In order to speed up a bit, you could add the following lines at the very
begining of the method _to_common_subfield(self, x, y) (lines 561-580)
{{{
if x._level == y._level:
return x._value, y._value
}}}
(when the level is the same I go from 3ms to 0.8ms)
What do you think about what I suggest in comment:15 namely, implementing
.is_finite() (returning False) and do something for Zmod(3) ?
