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...
Greetings
Nils Kattenbeck
