A namespace would not hurt but I really don't get why you don't consider 
classes a valid and rather helpful namespace.

1/ classes do not have to be instantiated.
2/ the fact that classes are more than a namespace is not an argument. 
Almost any object in python is able to do more than what you are 
actually using.
3/ Classes are used as much as 'is-a' than 'has-a', class instances 
*have* a state usually described by attributes
4/ "Although classes (and instances) are namespaces, ". You seem to 
contradict yourself. It was probably a rhetorical construct but it's 
rather confusing.
