Douglas Creager	b705664d49	[ty] Handle typevars that have other typevars as a default (#17956) ... It's possible for a typevar to list another typevar as its default value: ```py class C[T, U = T]: ... ``` When specializing this class, if a type isn't provided for `U`, we would previously use the default as-is, leaving an unspecialized `T` typevar in the specialization. Instead, we want to use what `T` is mapped to as the type of `U`. ```py reveal_type(C()) # revealed: C[Unknown, Unknown] reveal_type(C[int]()) # revealed: C[int, int] reveal_type(C[int, str]()) # revealed: C[int, str] ``` This is especially important for the `slice` built-in type.	2025-05-08 19:01:27 -04:00
