Dear list,

If I define two values

  val p : type out_channel -> blop -> unit
  val e : blop

then I can do something like

  Printf.printf "%a" p e

but I can't find a way to do something like

  Printf.sprintf "%a" p e

which is not well-typed. Is there any trick that I can use to avoid
changing the type of [p] to [blop -> string]?

Cheers,

Rodolphe
