I think this needs to take into account the current position of the iterator, since size_hint is supposed to return the remaining length, not the total length. |

As well as the above, it would be awesome to add tests for these |

Hi!
I've added
size_hintimpls for the iterators which can support it (while defaulting to 0 on Python-related errors).Should make
some_py_dict.iter().map(...).collect()faster by avoiding allocations!
