I believe it does. There was some discussion on python-dev and
with others in private email about how classes should be handled.
The relevant section of the specification is:
If a name is used within a code block, but it is not bound there
and is not declared global, the use is treated as a reference to
the nearest enclosing function region. (Note: If a region is
contained within a class definition, the name bindings that occur
in the class block are not visible to enclosed functions.)

If there was some other concern you had, then I don't know what it
was. I recall that you had a longish example that raised a NameError
