Douglas Creager f301931159 [ty] Induct into instances and subclasses when finding and applying generics (#18052) ... We were not inducting into instance types and subclass-of types when looking for legacy typevars, nor when apply specializations. This addresses https://github.com/astral-sh/ruff/pull/17832#discussion_r2081502056 ```py from __future__ import annotations from typing import TypeVar, Any, reveal_type S = TypeVar("S") class Foo[T]: def method(self, other: Foo[S]) -> Foo[T | S]: ... # type: ignore[invalid-return-type] def f(x: Foo[Any], y: Foo[Any]): reveal_type(x.method(y)) # revealed: `Foo[Any | S]`, but should be `Foo[Any]` ``` We were not detecting that `S` made `method` generic, since we were not finding it when searching the function signature for legacy typevars.		2025-05-12 21:53:11 -04:00
