The whole point of the functions it to allow doing snapshot-based
queries. It is indeed tricky, but that increases the need for
documentaton, no?
I think the last "more realistic code" section can be dropped,
it shows more user-friendly function but adds nothing new,
and the code is rather unreadeable.
