PHP - Understanding self::__construct() call

I came across a Wordpress widget that looked something like this

class my_widget extends WP_Widget {

   function my_widget() { return self::__construct(); }

   function __construct() {
     // Some code here
     ...
   }
}

add_action( 'widgets_init', create_function( '', "return register_widget('my_widget');" ) );

The __construct() will be invoked when an object is created. What help or functionality does the my_widget() function provide? Is it really needed? Any significance of that function having the same name as the class?

This just provide the backward compatibility for PHP4, nothing else.

For PHP4, my_widget is the constructor method, so it have to call __construct explicitly.

Looks like compability with PHP4... I would say that this code is weird.
