Check out this bit of Python magic!

class ListDict(OrderedDict):
    def __iter__(self):
        for v in self.values():
            yield v
            
    def __getitem__(self, item):
        if isinstance(item, slice):
            return list(self.values())[item]
        else:
            return super().__getitem__(item)

This way there is no need to call value.values. I can access the return values in both dictionary style and as a list! I think it's kinda brilliant. I can't take credit for it however :-) But I can freely use it!

Why bring complexity into this situation when you have a simple soultion? The ListDict may be a cute design but is verbose here and creates extra obstacle to the user.
