[middleware example] def middleware_generator(source_generator): it = source_generator() input_value = next(it) output_value = do_something_interesting(input_value) yield output_value The point that Chris made that you should be refuting is this one: >> What happens if do_something_interesting happens to raise >> StopIteration?
