To emphasize, you don't need to subclass "defaultdict" -- you need only subclass

You need to subclass and modify __missing__ to actually pass along the key:
--> class defaultdictkey(defaultdict):
... def __miss

Is there a way to set the default_factory of defaultdict so that
accesses to undefined keys get to set to the key?
i.e. if d['xxx'] were accessed and there was no key 'xxx' then
d['xxx'] would get set to 'xxx'
I know I can define a function with lambda for the default_factory,
