I have never found a prolem when using an interface was the only solution,
or even ANY kind of solution. The fact that your designs need it speaks
volumes of the problems with your designs.

There's your problem, then. You are wasting your time trying to implement
fancy design patterns just because design patterns are supposed to be
"cool". Loader class, Controller Base class, Front Controller - I have none
of that crap in my code, so I don't encounter the problems you have. When I
see code like "$this->load->library('email') " I just thank my lucky stars
that I don't have to maintain it. I think some serious refactoring is long
overdue.
Perhaps you are trying to implement something from another language and
expecting PHP to be just like that other language, which is always a stupid
mistake. PHP is different, therefore the solution will be different. I
suggest you learn how PHP works and design accordingly, and stop trying to
force it into emulating another language.
