That's what I expected.

Well, that's great as long as it is *your* foot. Unfortunately, when 
modifying a base class that other modules use you are not shooting your 
own foot - you are shooting the *other* guys foot (since your module 
will work happily with those modifications but the other modules won't) 
and that's not okay for a module system.
