I would prefer to have + in addition to |. I do not care
about *, but IMHO + is so intuitive and natural that
it is a pity not to have it (you can add lists, tuples,
strings with +, but not sets???)

So far my code used dictionaries with values set to None,
I expect that I will use sets soon, it will be more logical
and the code more readable.

daily work, production code, but so far I used lists or
dictionaries instead.
I am somewhat afraid of performance, until setrs are implemented
in C, though
