"(except private instance variables)" looks like a dig or a jibe. I would
have put it
"...Smalltalk-80 added [[metaclass]]es, to help maintain the "everything is
an object" paradigm by allowing classes to have their own specific state and
Perhaps they were trying to say that because Smalltalk lacks private
instance variables Smalltalk objects are not true objects, which is I
suppose arguable. But it makes poor sense to state that private instance
variables aren't objects; public inst vars aren't objects either.
