Comment (by JoelStransky):

 Here is a use case
 {{{#!php
 <?php
 add_filter( 'nav_menu_link_attributes', 'filter__nav_menu_link_attributes'
 , 10, 4 );
 function filter__nav_menu_link_attributes ( $atts, $item, $args, $depth )
 {
   if ( $args->has_children ) {  // PHP Notice:  Undefined property:
 stdClass::$has_children
     // modify $atts accordingly
   }
   return $atts;
 }
 }}}
