This may be a silly question: are there things in place to optimize this for the case where two strings are combined? E.g. highest character in combined string is max(highest character in either of the strings).

Also, this PEP makes me wonder if there should be a way to distinguish between language PEPs and (CPython) implementation PEPs, by adding a tag or using the PEP number ranges somehow.

Cheers,
