This is a ways off, if ever, but I think the general advice for user code is to use the newer protocol.
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 __iter__ instead.
So, for the purpose of writing new code, I think it justified to forget about or at least ignore the older iteration protocol.
This is probably valid as long as you don't need your code to work with any objects defined before the __iter__ protocol.
