I agree that the different semantics for lists and dicts are a strike
against this. The argument for it is that walking over a dictionary in
sorted order is (at least to me) a missing idiom in python. Does this
never come up when you're teaching the language?
I wouldn't advocate adding this to other types (e.g. Set) because
they're much less commonly used than dicts, so I don't think there's a
danger of a creeping plague of sort methods. Not a big deal though -
list.sorted() is the real win.
