Do they really need anything more sophisticated than:
def __repr__(self):
return "%s(%r)" % (type(self).__name__, self._subiter)
(modulo changes in the format of arguments, naturally. This simple one would
work for things like enumerate and reversed, though)
If the subiterators themselves have decent repr methods, the top-level repr
should also look reasonable.
Cheers,
Nick.
