We already have enough of a mess with save without making things even worse by trying to add moves into the mix. Also, non-copyable ranges have never really been a thing, and I really don't want to see things complicated even further trying to support such an uncommon use case. There are too many weird corner cases with ranges as it is. - Jonathan M Davis
