Yes, definitely. I hope no one misconstrued me to be suggesting that
you should use the 'sequence protocol' for iterators (e.g. using
__getitem__ and raising an IndexError). This is deprecated and is only
supported for backwards compatiblity. All new code should define

This is probably valid as long as you don't need your code to work with
any objects defined before the __iter__ protocol.
