>Take Symfony2's architecture, for example. Controllers, Entities, Repositories, Views, Services, Listeners, Events, etc. Each layer has its own distinct purpose that do something very specific by themselves, but when brought together form a very cohesive whole. But the end result is so very complex and the benefits gained are doubtful at best.
