Extend the WP_Widget_Factory class by overloading the register method to allow for passing params

extend_wp_widget_factory.php

Class Extend_WP_Widget_Factory extends WP_Widget_Factory {

	// Overload register($widget_class) with ability to pass parameters into widgets
	function register($widget_class, $param = null) {
		$this->widgets[$widget_class] = new $widget_class($param);
	}

}

This is exactly what I want to do, has 3 widgets which differ only by name, while everything else is equal. I tried your code and it seems to work, it's ok to steal it and use in my function.php without something goes wrong in wordpress?
