[New-bugs-announce] [issue45605] Return False from __contains__ method if object not hashable for set and dict

[Андрей Казанцев]

New submission from Андрей Казанцев <heckad at yandex.ru>:

Now if do something like `[] in set()` python raise an exception, but if an object isn't hashable then we know for sure that it isn't in the set. Propose return False for these cases.

P.S. I would like to make a patch
