Great PEP overall. We definitely don't want the restriction to grouping numbers
only in threes. South Asian crore use grouping in twos.

Interesting... 3 digits in the least significant group, and _then_
by twos. Wouldn't have predicted that one! Never bumped into that
notation before!
The first time I used underscore separators in any language, it was a test
script for a server that wanted social security numbers as integers instead of
strings, like 123_45_6789.[^1]
Which is why I suggested the style guideline should just say "meaningful grouping of
digits", rather than try to predict what counts as "meaningful" for every program.
[^1] Of course in Python, it's usually trivial to stick a shim in between the database
and the model thingy so I could just pass in "123-45-6789", so I don't expect
to ever need this specific example.
Yes, I had thought of the Social Security Number possibility also,
although having them as constants in a program seems a bit unusual. Test
script, fake numbers, yeah, I guess so.
