描述

In response to this comment

I think the idea here would be to recommend removal of arguments that are ignored and never referenced.

On the flip side, I'm wondering if it would make sense to also lint for used arguments starting _ which recommends removing the _, because that came up in the same review.

研究方向
To implement this lint, examine how existing unused argument lints work in Clippy (e.g., `unused arguments`). The issue references a comment in PR #3203 which discusses the idea. The lint should detect function arguments that start with ` ` but are never used in the body, and optionally warn when a ` ` argument is used. Start by looking at the Clippy lint collection in `clippy lints/src/` and the Rust compiler's `rustc lint` API. The discussion may have further guidance on naming and behavior.
