but how do we protect a member variable, assuming 'protected' means that the 
variable is only accessible by certain objects? i was hoping there was a 
simple default way to check whether a calling class is a 'friend' allowed to 
access protected members, or perhaps this could be a chance to check wether 
that would be useful a concept to have in gnustep.

putting the private methods into a separate category does not make the 
compiler enforce privacy, correct?

that is actually how i implemented it, i only called it 'get' in the message.
