Cf. https://groups.google.com/forum/#!topic/fa.caml/fOfJVpHywW0 text from Gabriel Scherer:

let delayed_sprintf fmt = Printf.sprintf (fmt ^^ "%s");;
# let result = Printf.sprintf "%d) %s\n" 3 "foo";;
val result : string = "3) foo\n"
# let thunk = delayed_sprintf "%d) %s\n" 3 "foo";;
val thunk : string -> string = <fun>
# thunk "";;
- : string = "3) foo\n"
