jQuery Event Namespacing

Just found this blog showing how to namespace events in jQuery:

(function($){
    $.fn.extend({
        clicked: function() {
            return this.bind('click.clicked', function() {
                $(this).addClass('clicked');
            });
        },
        unclicked: function() {
            retun this.removeClass('clicked').unbind('click.clicked');
        }
    });
})(jQuery);

The same blog also contains a Plugin Development Pattern which I highly recommend for anyone developing jQuery plugins.
