How to set multiple `orderby` in query argument?

Advanced ordering feature is now added in the new version of WordPress. I came to know this after release of WordPress 4.0.

Check this announcement for more detail.

Example:

$q = new WP_Query( array( 'orderby' => array( 'title' => 'DESC', 'menu_order' => 'ASC' ) ) );
