I suspect you're being bitten by http://docs.python.org/dev/reference/datamodel.html#special-method-lookup In particular: "implicit special method lookup generally also bypasses the __getattribute__() method". __init__() is a special method. The default __getattribute__() implementation consults an object's __dict__. type.__new__() presumably does an implicit special method lookup for __init__() behind the scenes. Hence, your custom __dict__ is bypassed. Cheers, Chris -- http://blog.rebertia.com -- http://mail.python.org/mailman/listinfo/python-list
