And that’s EXACTLY why none of the functions on Sequence should rely on the order conveying meaning. `ElementsEqual` (for example) DOES rely on the order of iteration conveying a meaning not required by the protocol, and renaming it `lexicographicallyEquals` does not change that fact. Either Sequence needs to require a meaningful order or `elementsEqual` should be moved to a protocol that does.
