The same reasoning applies here. I had a bug like this and it was data-dependent, hard to reproduce, and there was no exception to hook a debugger onto or stack trace to give information.
And now it will raise an exception at the point where the error actually occurred.
It won't because I wasn't using generators. The point II have been trying to make is that this isn't just about generators.
Having gone through that experience I would have thought you would be more in favor of the change.
On further reflection I am more in favour of the change. My initial thought was that it places the emphasis in the wrong place. I had concluded that the focus should be on the inappropriateness of next() and I still think that but that doesn't mean that the PEP isn't a good thing in and of itself.
