Is there a lint to prevent underscore prefixed bindings (_foo) for must_use types?

Hi

I'm working on a code base where we would like to make sure that #[must_use] types are really used (specifically for Result).

I see that let_underscore_must_use exists, however this does not trigger on bindings that use _ as a prefix with a name (let _foo = ...).

Is there any way to prevent the latter too?
