[New-bugs-announce] [issue30100] WeakSet should all discard and remove on items that can have weak references

[donkopotamus]

New submission from donkopotamus:

Currently WeakSet().discard([]) will raise a TypeError as we cannot take a weak reference to a list.

However, that means a list can never be in a WeakSet, so WeakSet().discard([]) could instead be a no-op.  Similarly WeakSet().remove([]) could be a KeyError.
