Unused type parameter

Reports unused type parameters.

func main() {
 printAll(
  42,
  "bird",
 )
}

func printAll[I int, S string](
 i I,
 s string,
) {
 fmt.Println(i)
 fmt.Println(s)
}

The printAll function has two type parameters I and S but uses only the first of them. Therefore, the S string is grayed out.
