2. it's already trivial to achieve such chained lookups in 3.3 by passing a collections.ChainMap instance as the globals parameter: http://docs.python.org/dev/library/collections#collections.ChainMap
Somewhat OT, but collections.ChainMap is really cool. I hadn't noticed it get added into 3.3, and as far as I can see, it's not in the "What's New in 3.3" document. But it's little things like this that really make the difference for me in new versions.
So thanks to whoever added it, and could we have a whatsnew entry, please?
Paul.
