Someone correct me if I'm wrong:
Smalltalk implements four scopes for variables:
instance variables: scope of one instance.
class variables: scope of a class and subclasses
classInstance variables: scope of one class (separate "copy" for each
subclass)
pool dictionary variables: scope of one class and it's instances (*not*
for subclasses)
In a hierarchy of classes where a parent class have classInstance variables,
each subclass will hold a "private" own variable (with the common name
defined in the parent class).
For instance, Parent may declare classInstanceVariableNames: 'default'
and each subclass of parent will define their own default value, but they
may share methods that call "self default".
Hope it helps,
Ricardo
