Might be me being stupid.. but if these new rules are in place, what will
the difference between class variables and instance variables (of class
objects) be?

The only thing coming to my mind, is that class variables are easily
accessed from instance methods, while you need to do
"self.class.class_eval{@my_class_instance_var}" for class-object instance
variables.

BTW: Just for the sake of being curious... is it possible to define
class-variables of the class Class?
