If I understand correctly, the idea is to get rid of friend but still let 
some things look inside of others. This solution lets closed set of code 
interact at a low level while doing encapsulation at wider scopes. The reason 
friend is discarded is that it has the power to do arbitrary snooping which 
causes the same kind of problems as goto's arbitrary redirection causes.
