Can somebody please explain this to me:

This works as expected:

# let s = Printf.sprintf "%s" "enigiets";;
val s : string = "enigiets"

But this not:

# let q = "%s";;
val q : string = "%s"
# let s = Printf.sprintf q "enigiets";;
Characters 23-24:
This expression has type string but is here used with type
  (string -> 'a, unit, string) format

Why?
