Maybe it makes sense to add a note in the PEP saying this is not an exclusive list and some more classes can be made generic in the future if needed, but this is almost obvious, so I think it is up to the PEP author. -- Ivan On Mon, 11 Nov 2019 at 16:50, Guido van Rossum <guido@python.org> wrote:

FWIW WeakSet will be registered as MutableSet in 3.9.

Hello,

after being told in issue 38756 of the python bug tracker that PEP 585 will add generic typing to many standard collections/containers I looked at which types will get generic versions. I noticed that collections from weakref were not included (WeakDictionary, WeakSet etc). WeakKeyDictionary and WeakValueDictionary should probably automatically be generic as they extend _collections_abc.MutableMapping but WeakSet does not. Would it be possible to clarify that WeakDictionaries or subclasses in general will become generic but more importantly I think it should be worth considering add WeakSet to the PEP

I would like to hear your thoughts on this topic...
