I hope not. The set of potential functions that operate
on iterators is open-ended, and there's no reason to
single out a particular subset and make them methods.

Also, it would force all iterators to inherit from a
common base class in order to support those methods,
which is not a Pythonic thing to do.

Strings are different, because (a) they're a concrete
class, and (b) string methods benefit from having
access to implementation details of the string.
