I think it's good

Yes, it will demand safe and well-defined behavior from Iterators.

Swift is already a very safe language, and producing undefined behavior if someone calls the iterator too often is not nice. Since most iterators already behave nicely (or maybe all?) this shouldn't be a big issue.

not sure

I read the proposal.
