these capabilities need to settle for a sensible pointer only if they have to participate in the widget’s life time administration. If not they should settle for a widget*, if it can be nullptr. Otherwise, and ideally, the function must accept a widget&.
By producing on to the target things, we will get only the basic warranty rather then the sturdy guarantee supplied by the swap procedure. Watch out for self-assignment.
