works here :)

Python 2.3.4 (#2, Jul  5 2004, 09:15:05)
[GCC 3.3.4 (Debian 1:3.3.4-2)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> class pupa(dict):
...    def __getattr__(self, attr):
...        return self[attr]
...    def __setattr__(self, attr, val):
...        self[attr] = val
...
>>> larva={'a':1,'b':2}
>>> moth=pupa(larva)
>>> moth.a
1
>>> moth.b
2

unless you mean something else by "this doesn't work"
