Jonathan Chaffer has written a very interesting article which explains how the CMS Drupal (which powers this site, btw.) uses many OOP principles and Design Patterns without using PHP's class keyword. It's written purely procedural, while still using the best features the OOP world has to offer.

The main message IHMO is this: OOP != classes.
