It appears (to me) that if one wants to access a class variable from an
instance method, accessor methods need to be provided. Am I missing
anything on this? Thanks.

Class variable? (@@var): no. You can simply access it.
Class INSTANCE variable? (@var, at class scope): absolutely, you must define accessor methods.
IMHO, you should be accessing ALL state (instance or class) via accessor methods. This makes refactoring and changing the design _much_ easier.
