I vote for the latter option. Particularly if something like Namespace objects 
make their way into the standard lib before Py3k (a Namespace object is 
essentially designed to provide attribute style lookup into a string-keyed 
dictionary- you can fake it pretty well with an empty class, but there are a 
few quirks with doing it that way).
