Currently I'm planning to implement the following behavior for rewind(): * If before first yield: Resume to first yield (this priming behavior is common to all the Iterator methods) * At first yield: No-op * After first yield: Recoverable fatal error So this would allow you to call ->rewind() after creating the generator, but will throw an error if you try to do so later. Another thing that I'd like to do is drop the ->close() method. It doesn't really make sense to explicitly close generators. Any objects to those two things?
