Usage when working over menus order

$firstm = $lastm = false;
$i = 0;

foreach ( $menu as $order => $top ) {
        $i++;

        if ( 0 == $order ) {
            $menu[0][4] = add_cssclass( 'menu-top-first', $top[4] );
            $lastm = 0;
            continue;
        }

        if ( 0 === strpos( $top[2], 'separator' ) && false !== $lastm ) {
            // if separator
            $firstm = true;
            $c = $menu[ $lastm ][4];
            $menu[ $lastm ][4] = add_cssclass( 'menu-top-last', $c );

While the function name does suggest no limitation on its availability, it is defined in wp-admin/includes/menu.php, so is not immediately available on the frontend (and use on the frontend is probably discouraged).
