I think it's helpful to know what type was unused when looking at these warnings. The type will likely determine whether the result *should* be used, or whether it should just be ignored. Including the type also matches the behavior of the `must_use` lint: unused `SomeType` that must be used.

There was a problem hiding this comment.
Alternatively, the type could be displayed in a note, but using the title is consistent with unused_must_use and easier to scan IMO.
