arbitrarily nested scopes, at least. the old local/global/builtin
approach (the LGB rule) is of course a kind of nesting; the new thing is
support for "enclosing scopes" in Python 2.1/2.2 (the LEGB rule). for
some background, see:
http://www.python.org/dev/peps/pep-0227/
the section "Rebinding names in enclosing scopes" discusses the 2.X-
specific thinking; this may be revised in 3.0 (see current python-dev
discussions).
