Error for mismatched types involving generics seems to be missing something

[camelid]

pub fn f<T>(a: &T) -> *const T {
    &1 as *const i32
}

(Playground)

The error includes a label that says "this type parameter", but it doesn't complete the sentence:

   Compiling playground v0.0.1 (/playground)
