 Indeed, thanks! I meant `mt_rand()` without any parameters, in that case
 `$max` defaults to `mt_getrandmax()`.

 I guess `wp_rand()` too should have used `null` as the default value for
 both parameters, so that we could differentiate between `wp_rand()` and
 `wp_rand( 0, 0 )`, which is not currently possible as zero is the default
 value. But it's too late to change that now without security implications.
