to work. It works out-of-the-box for my scheme. It can be made to work with a subclass of dict for the D'Aprano scheme.

This raises the question about this advantage (I agree it could be an advantage): is providing such a subclass really such a heavy lift? Additionally and related: what would be the real world advantages of d[x=1, y=2], where d is just a vanilla dict, working right out of the box?
