Currently to annotate a generator, something like `Generator[str, None, None]` is required. Which is a bit confusing and verbose. Can we allow shorthand, like `Generator[str]` for simple cases? I'm not entirely certain what the semantics ought to be... Maybe Generator[t1, t2=Any, t3=None] ? |

Is Iterator[Whatever] not sufficient for you? |

Actually yes it is sufficient. I don't know why I didn't think of that! Perhaps some note in the docs could help other lost children of Python :P |

If you would like to propose a doc fix, then please go ahead and make a PR. |

It is already documented, with examples. I do not think the documentation can be made better. |

Actually Serhiy is right, I just checked and found this sentence: ``` Alternatively, annotate your generator as having a return type of either Iterable[YieldType] or Iterator[YieldType] ``` |

Clearly my attention span does not exceed 5 paragraphs, so sorry! |
