This discussion reminds me of Eiffel’s access system. Instead of having these generic “public/private” distinctions, in Eiffel the programer specifies exactly which methods can be used by which classes. So a “public” method would be defined as accessible to “[Any]” and a private method would be defined as accessible to “[Self]”. If you want to grant access of a particular method to only particular helper classes, you would specify them.
Having a system like that would solve Karl’s problem because it wouldn’t matter what physical file the classes are in.
That sounds absolutely horrible. Keep building walls and ultimately you'll
never leave your bike shed.

That IMO is the only sensible solution. Everything else -even in the name of simplicity- will be insufficient and complicate matters.
