Review comment:
Latest works by picking the Latest based on the timestamp. I do not recall
with Create does but it may use the same timestamp for its elements, or
potentially an implementation could do that. Perhaps it would be more explicit
to use elements with Timestamps, otherwise the output could be arbitrary.
