[Typing-sig] Re: Thoughts on a typing.Self?

Sorry, just to be a bit clearer, I am asking about being able to do: ```py class LinkedList(Generic[T]): value: T next: Self | None = None class OrdinalLinkedList(LinkedList[int]): @property def ordinal_value(self) -> int: ... reveal_type(OrdinalLinkedList(value=1, next=OrdinalLinkedList(value=2)).next) # revealed type is OrdinalLinkedList ```
