Smarty templates are a very useful tool and I'm addicted to Smarty for a couple of years now. All projects I did use Smarty templates. Now it's 2009 and PHP 5.2 is stable and has a good performance. Therefore I decided to use any of PHP 5's features when they come along my way.

Recently, Iterators came to close and I had to implement one. It's usefull for proxying and also for dynamically presenting views of lists. Therefore my implementation looks like:

class Foo {
  var $childs;
