Speaking of slots, I've often been annoyed that there is no abstraction
that hides the difference between instances that use a dict as symbol
table, and those that use slots. (And those that use both.)

it would be nice to
ignore the implementation details and just have a "symbol table" object
to work with. What do you think?
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.
