Let me see if I understand.  Suppose we have class "animal" with
subclass "cat", each of which have variables:

animal:
    variable a
    variable b

cat:
    variable c

And we have an instance of "cat", called "sylvester".  In sylvester's
methods, we can use variable "c" without declaration; and we can
use variable "a" and "b" if we qualify them with the  
namespace ::animal::.

Is that right?
