Subject: Re: Subclasses and constants

@@class_variables seemed to have the same behavior - if they were
changed in the subclass, and the parent defined a method, it wouldn't
have access to the subclass's definition.

(BTW - of course Constants don't change - but different subclasses
could have different ones - with them never changing - but I digress)
