I'm not sure I really followed this argument.  Perhaps some code
examples would help.

The ability to access class attributes via self is pretty fundamental
property of Python.  I don't expect it will go away.

Also note that nested scopes do not allow access to class attributes
as unqualified names.  When resolving free variables, class scopes are
skipped.  This decision was made because we wanted to enforce the rule
that all access to class and instance data should be via self.

Write a PEP.
