I still prefer Werner Schiendl's idea of iter.reversed, IF we find a
way to have builtin function iter grow a 'staticmethod' of sorts...!

It's inappropriate for itertools according to detailed criteria that
Raymond has recently posted here.

Yes, builtins should indeed be reserved strictly for the indispensable
cases (and trimmed a LOT in 3.0 -- but that's years away).  Which is
why, e.g., list.sorted was made a classmethod of type list, rather
than a built-in.  Similarly, IF iter was a type, iter.reversed would
be the "one obvious way to do it"...
