which do you want, instance variables or class variables? they're both 
inherited by subclasses, just as both kinds of methods are. there is 
only one instance of each _class definition_, and hence only one 
instance of class variables and class methods. unless you redefine them 
in the subclass, the ascentor's class methods will be used.
