Why is this confusing? The operation you want to perform is "give me
an object from this set, I don't care which one".

That's not an operation that applies just to sets, you can do it with
an iterable, therefore the spelling is one that works with any
iterable: next(iter(s))

This entire thread is like asking for s.length() when len(s) already works.

Cheers,
Nick.
