Python has the same "incoherent" model and people constantly write abstractions based on iterables in Python. Iterators are claiming to be iterables, which is true. They are iterable. You can iterate over them. It has well-defined behavior and a lot of programs do it. It's disappointing to see arguments in TC39 notes and on es-discuss that are contradicted in the clearest possible way by ten years of experience in a widely used language. -j _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
