Thanks, Justin; that occurred to me, too. But the following results in
"Notice: Undefined variable: factorial":

  $factorial = function($n) use ($factorial) {
      if ($n == 1)
        return 1;
      else
        return $n * $factorial($n - 1);
    };

  print $factorial(3);

and eventually "PHP Fatal error:  Function name must be a string."
