Oops, I was indeed confused. I think I meant this:

def keys(self):
    return [k for k, c in self.__dict.iteritems() if c.objptr is not NULL]

Was I not clear, or am I missing something entirely? keys() needs no special treatment, but items() and values() do:

class celldict(object): ...

def keys(self):
    return self.__dict.keys()

def items(self):
    return [k, c.objptr for k, c in self.__dict.iteritems()
            if c.objptr is not NULL]

def values(self):
    return [c.objptr for c in self.__dict.itervalues()
            if c.objptr is not NULL]
