Flag a parameter of a wise pointer sort (a kind that overloads operator-> or operator*) that is copyable/movable but under no circumstances copied/moved from in the perform overall body, and that is under no circumstances modified, and that isn't passed along to a different perform that would do this. That means the ownership semantics aren't applied.
