Douglas Creager 2214a46139 [ty] Don't use implicit superclass annotation when converting a class constructor into a Callable (#22011) ... This fixes a bug @zsol found running ty against pyx. His original repro is: ```py class Base: def __init__(self) -> None: pass class A(Base): pass def foo[T](callable: Callable[..., T]) -> T: return callable() a: A = foo(A) ``` The call at the bottom would fail, since we would infer `() -> Base` as the callable type of `A`, when it should be `() -> A`. The issue was how we add implicit annotations to `self` parameters. Typically, we turn it into `self: Self`. But in cases where we don't need to introduce a full typevar, we turn it into `self: [the class itself]` — in this case, `self: Base`. Then, when turning the class constructor into a callable, we would see this non-`Self` annotation and think that it was important and load-bearing. The fix is that we skip all implicit annotations when determining whether the `self` annotation should take precedence in the callable's return type.		2025-12-16 13:37:11 -05:00
