Some of these didn't seem right when I tried them with object() instances. How did you come up with this set of methods?

These 4 definitions will break mypy. It's best to leave them out and potentially file a separate issue about these.

These don't seem to exist in Python 3.5.1: __del__, __bytes__, __bool__, __getattr__, __get__, __set__.

These don't seem to exist: __get__, __set__ and __delete__

If you looked up these from documentation, you should be aware of that (Python) documentation is not to be trusted as a source of truth when creating stubs -- docs tend to have too many inaccuracies and outright errors. |

Yeah I tried looking at the CPython code, but I didn't quite get what is happening there. I checked for existence of the methods with the interpreter and removed the ones which failed. The 4 comparison operators are taken out. A pull request for mypy, which would allow defining them, is here: python/mypy#2584. |

Adds special methods for
objectas per #773.3.6 also added
__set_name__, but I'm uncertain if simply creating the directorystdlib/3.6would suffice to add 3.6-specific type hints.There are also still missing special methods, like
__prepare__: I'm just confused to which class they belong.
