(Easy) An assignment operator ought to return T& to allow chaining, not alternate options like const T& which interfere with composability and putting objects in containers.

† swap throwing: It is really typically achievable to reliably swap data users which the objects keep track of by pointer, but non-pointer facts associates that don't have a toss-totally free swap, or for which swapping has to be executed as X tmp = lhs; lhs = rhs; rhs = tmp; and copy-design or assignment may possibly toss, still have the probable to are unsuccessful leaving some details users swapped and others not.
