Alex: I dislike that as much as I dislike [] as a shorthand for list(), but I have no trouble admitting that if we have the [...] form, it's consistent to have the {...} one too.

Greg: So it really does come down to finding an unlikely-to-confuse notation for the empty set? If people would like to send me suggestions, I can try an experiment in class (I start teaching a new crop of second-year students Python in May).

Thanks, Greg
