[issue25864] collections.abc.Mapping should include a __reversed__ that raises TypeError

Guido van Rossum added the comment: This sounds good. Also, reversed() could then be modified to produce a better error. (The "unhashable" error comes from the hash() builtin, so that's also a precedent.) On Sat, Dec 26, 2015 at 4:32 PM, Andrew Barnert wrote: > >

[issue25958] Implicit ABCs have no means of "anti-registration"

Andrew Barnert added the comment: As Guido pointed out on -ideas, hashing already uses the convention of `__hash__ is None` to declare a type unhashable, and `collections.abc.Hashable.__subclasshook__` already checks for that. Meanwhile, setting `__iter__` and `__reversed__` to `None` already

[issue25864] collections.abc.Mapping should include a __reversed__ that raises TypeError

Andrew Barnert added the comment: As mentioned in #25958, Guido pointed out on -ideas that `__hash__ = None` is already the standard way to declare a class unhashable, and it's recognized by `collections.abc.Hashable`. Doing `__reversed__ = None` does make `reversed(m)` raise a `TypeError`
