Hi all.
What would people's reaction be if a class was prevented from being able to
directly access its superclass's instance variables? A subclass should use
accessor methods to access a superclass's instance variables.
Is there any particular reason subclasses get access to superclass instance
variables? I think it breaks encapsulation.
If this was implemented, it might be possible to avoid needing to recompile
every subclass when you modify the instance variables of a class.
Gulik.
