I see you misunderstood my observation:  Python does not consider a class
definition as a separate namespace *as it does* for function definitions.

Of course classes are separate namespaces, or they would not work at
all.  However,
Python does not automatically search class namespaces -- even within the class
definition -- *as it does* within function definitions.

That is the key insight I was seeking.  To search a class namespace one must
qualify the lookup with the class or instance name.
