title: Print tuple in OCaml
body: <p>I want to print the result of a method which is of type <code>int * int</code>.</p>
  
  <p>I tried like this:</p>
  
  <pre><code>printf "%d %d\n" (find (99, 10));;
  </code></pre>
  
  <p>However, I'm getting:</p>
  
  <pre><code>Error: This expression has type int * int
         but an expression was expected of type int
  </code></pre>
  
  <p>I looked here <a href="http://caml.inria.fr/pub/docs/manual-ocaml/libref/Printf.html" rel="nofollow">http://caml.inria.fr/pub/docs/manual-ocaml/libref/Printf.html</a> but there is no mention of tuple.</p>
  
  <p>So what's the right way to print a tuple?</p>
