I think that would be great -- and wonder if vars() could be extended to do that?

I think it is. Apart from a matter of taste, what part of the analogy
do you feel is invalid?

For my part, I think the difference is that when you are working with .__dict__ you are doing meta-programming, for which poking around in the dunders makes perfect sense.
