[f9 AS3] Declaring an instance of each class

This will sound odd, but I would like to find a way for Flash to declare one instance of each class inside a package. That is to say, if a package com.rezmason.stuff contains five classes, some code makes an instance of each class in an array; but if, later on, I take out two classes, that same code only makes an instance for each of the three remaining classes within the package. Later still, if I add seven classes, the same code makes an instance fore each of those ten classes.

I doubt that this is possible, but I figured that if anyone would know, it would be you folks. Code with this kind of flexibility would greatly simplify managing the code in a project that frequently has classes being added, removed and swapped. If anyone has an idea, I’d like to hear it.
