Subject: [Caml-list] Printf question

I want to define a wrapper function for printf, basically for debug.  I'd 
like it to work so I can do things like:

    debug "some message"; (* outputs "FOO: some message\n" *)
    debug "answer: %d" 42 ; (* outputs "FOO: answer: 42\n" *)

basically to prepend "FOO: " and append "\n".  Is this possible in any 
sane manner?  I tried:

let debug s = Printf.printf ("FOO: " ^ s ^ "\n")

and:

let debug s = let t = "FOO: " ^ s ^ "\n" in Printf.printf s

and neither works.

Brian
