Preparing for the New DIP Process

[Dom DiSc]

If you have difficulties to see the logic of module-private, 
think of a module as a flat:
If you don't want someone to mess with your private stuff, don't 
live with him in the same flat! Be ensured, locks on every 
cupboard won't do. You cannot prevent someone within the same 
flat from messing with your private stuff. Most people realize 
that at some point in their life, so only few live together in 
the same flat.
I hope you will also realize at some point in your life, that two 
classes should not live in the same module - except they are 
close friends.
