because inheritance is not always optimal.
What's the problem that's outlined? I'm too lazy to go and look :|
/**
* CI_BASE - For PHP 4
*
* This file is used only when CodeIgniter is being run under PHP 4.
*
* In order to allow CI to work under PHP 4 we had to make the Loader class
* the parent of the Controller Base class. It's the only way we can
* enable functions like $this->load->library('email') to instantiate
* classes that can then be used within controllers as $this->email->send()
*
* PHP 4 also has trouble referencing the CI super object within application
* constructors since objects do not exist until the class is fully
* instantiated. Basically PHP 4 sucks...
*
* Since PHP 5 doesn't suffer from this problem so we load one of
* two files based on the version of PHP being run.
*
* @package CodeIgniter
* @subpackage codeigniter
* @category front-controller
* @author Rick Ellis
* @link http://www.codeigniter.com/user_guide/
