PEP 791: imath --- module for integer-specific mathematics functions

Sorry, I don’t see it.

This section mention the intmath PyPI package. I don’t see good reasons to change naming here, it’s just a way to provide same namespace for old releases:

import intmath
import math
math.integer = intmath

vs

import math.integer

I see only one place in the section, related to isqrt. Will fix.
