Comment:
I think I made it work. See attachment.
Implementing the category can result in a slow-down in the creation of
parents. Let's see what happens here. Without the patch:
{{{
sage: %time L = [Zp(p) for p in prime_range(2,10^4)]
CPU times: user 2.00 s, sys: 0.09 s, total: 2.09 s
Wall time: 2.09 s
}}}
With the patch:
{{{
sage: %time L = [Zp(p) for p in prime_range(2,10^4)]
CPU times: user 2.10 s, sys: 0.05 s, total: 2.15 s
Wall time: 2.15 s
}}}
I hope that's acceptable.
