Yes, that's my main use case -- presenting results to the user, so they need
to be in alphabetic order (ascii_lowercase actually, but it's much the same).
Anyway, Guido has already pronounced on such enhancements as "Too
Clever", so we have to keep ascii_lowercase &c as plain strings without any
enhancements and keep the "false positives" &c on 'in' checks.
