Python sooooo dynamic, but it lacks a (builtin) X-class ready for ad-hoc usage just like dict() :-)
I have in almost every app/toolcore-module this one:

------

class X(object):
    def __init__(self,_d={},**kwargs):
        kwargs.update(_d)
        self.__dict__=kwargs
class Y(X):
    def __repr__(self):
        return '<Y:%s>'%self.__dict__

------

x=X(spam=1)

Maybe X should be renamed to __builtin__.Object ...
