I disagree with this. saving a range should always be the caller's
responsibility/choice.

If the argument "people expect the range to be saved" prevails here, it means
"save" is failed as a concept, and forward ranges should simply be defined as
"ranges that implicitly save on copy": EG no need for save, only for a postblit
that's *always* called.
