I think the "dicts are like more-featured" sets is a math-geek perspective,
and unlikely to make things more clear for the bulk of users. And may make
it less clear.

We need to be careful -- there are a lot more math geeks on this list than
in the general Python coding population.

Simply adding "+" is a non-critical nice to have, but it seems unlikely to
really confuse anyone.
