Assignments and globals

[echuck3 at my-deja.com]

Here's a very distilled version of my problem:

settings = { 'x': {},  'y': {} }
class K:
    def foo(self):
        settings = settings['x']
K().foo()

I get "Name error: settings" on this. If I change the line to:
        s = settings['x']

Then everything works. It appears that in the statement 'a = b', Python
starts mucking with the namespace before b is evaluated.

Is there a good reason for this? Is it even a design point, or an
accident of implementation? I wonder if JPython has this problem.
