研究方向: Examine the test case example comment at https://github.com/rust lang/rust clippy/issues/380#issuecomment 2862315757 to understand expected behavior. Look at existing similar lints in Clippy, such as those in clippy lints/src/, for pattern matching. The implementation should detect when a generic parameter name shadows a type name defined earlier in the same scope.
