 Hey Ben,

 First, some context:

 The whole API related to add_submenu_page() needs a lot of work. The logic
 is spread all over the place and is mixed with the menu generating code
 #12718.

 Also, add_submenu_page() already has 6 parameters. If we want to add
 another parameter, we should think about converting them to an associative
 array first.

 Instead of adding yet another parameter that only works for this function
 and create an inconsistency with add_menu_page(), we could add a helper
 callback that just loads a file you specify.

 Example usage:

 {{{
 add_submenu_page( 'tools.php', 'My Utility', 'My Utility',
 'manage_options', 'my-utility', _delayed_load( 'my_template_file.php' ) );
 }}}

 And here's how the implementation of _delayed_load() would look like:

 {{{
 function _delayed_load( $file ) {
         return function() use ($file) {
                 include( $file );
         };
 }
 }}}

 This only works in PHP 5.3, but it can be made to work for PHP 5.2 by
 using a helper class.
