Hi,

Are you thinking of __prepare__? I did to but I read the details of this:

http://docs.python.org/py3k/reference/datamodel.html#customizing-class-creation

The class body can be executed "in" any mapping. Then I’m not sure but 
it looks like type.__new__ only takes a real dict. You have to do 
something in your overridden __new__ to eg. keep the OrderedDict’s order.
