Another issue is that it breaks the way I and others have taught for years that generators are a kind of iterator (an object implementing the iterator protocol) and that a primary motivation for generators is to provide a simpler and more direct way of creating iterators. However, Chris explained that, "This proposal causes a separation of generators and iterators, so it's no longer possible to pretend that they're the same thing." That is a major and worrisome conceptual shift.

I agree with Raymond on this point.
