Now that dicts are ordered[1], would it by any chance make sense to also order sets?
A use case that I ran into is trying to reproducibly get a random.choice from a set (after calling random.seed).
At first I did not need reproducibility, and I just called random.choice(list(my_set)).
Later when I did need it, it was difficult to find out what was wrong. Then I realized that sets are unordered, and that order is not dependent on random.seed.
It seems there are also some other confused newbies out there.[2][3]
Thank you for the powerful language that is Python!
