FAQ.six: Have these rules been accepted from the ISO C++ specifications committee? Do they characterize the consensus of the committee?
Flag a parameter of a sensible pointer variety (a kind that overloads operator-> or operator*) that is definitely copyable/movable but hardly ever copied/moved from in the functionality overall body, and that is under no circumstances modified, and that's not handed alongside to another operate which could accomplish that.
