Объектные массивы в 5.3

Салют!

Есть кто работает с массивами как с объектами? Я в доктрине нашел хорошую объектную реализацию массива, совместимую с обычными массивами пхп, можно работать, используя объектный интерфейс, и, как в груви или руби, используя замыкания map, filter и др. Кто- нибудь пробовал их или может есть другие популярные реализации?

а я все время сидел на array() . А ЭррэйОбжект из ПХП ничего. Только он не 5.3 я там замыканий не увидел. а новый 5.3 ЭрэйОбжект случайно не знаешь будет?

 

что - то не похож он на интерфейс

PHP:

1. <?php
2. $x= new ArrayObject(array(1,2,3));
3. print_r($x);

output:

самому? или уже где-то выложили?
