    The complex class has special methods which always raise a TypeError:

    __int__
    __float__
    __floordiv__
    __mod__
    __divmod__

    After removing them the corresponding operations (converting to int and float, operators // and %, function divmod()) will still a TypeError.

    Advantages of removing:

    • Less code to maintain.
    • More uniform error messages.
    • Clearer output of help().
    • Possibility to implement a type with __rfloordiv__, __rmod__ and __rdivmod__ which support complex numbers.

    The docs for this should probably be updated to reflect the change: https://docs.python.org/3/library/typing.html#typing.runtime_checkable

    Indeed, Bartosz. Do you think you can help by submitting a PR for the docs?
