Agreed, I think it's worth having an explanatory PEP at least for
documentation purposes. It also makes it easier to reference from the 3.5
What's New, as there may be some code that's relying on the current
behaviour that may need adjusting to use a custom exception type rather
than StopIteration (or else refactoring to avoid crossing a generator frame
boundary).

Nick.
