I think the renaming of next() to __next__() is a good idea in any case. It is distant enough from the other issues that it can be done independently of any decisions about __iter__.
Yeah, it's just a pain that it's been deployed in Python 2.2 since last December, and by the time 2.3 is out it will probably have been at least a full year. Worse, 2.2 is voted to be Python-in-a-Tie, giving that particular idiom a very long lifetime. I simply don't think we can break compatibility that easily. Remember the endless threads we've had about the pace of change and stability. We have to live with warts, alas. And this is a pretty minor one if you ask me.
Is this a Pronouncement, or are we still waiting on the results of the survey? Note that several people have suggested a multi-release strategy for fixing this problem; does that make any difference?
