描述

~~Is there ever a reason to have an unsized type and ref it instead of having a reference to an unsized type?

I think we should simply suggest to use let p: &str = &*"hello"; instead (and make sure our quoting code erases &* or sth)

E-medium because I'm wary of weird consequences for cases I didn't think about.~~

make sure our quoting code erases &*

研究方向
Examine clippy's suggestion formatting code, likely in clippy lints/src/utils/mod.rs or similar. The task is to ensure that `&*` is erased from suggestions (not added with parentheses). Look for where `&*` patterns are generated and modify the quoting logic accordingly. Check issue comments for any additional context or constraints.
