Copy-and-swap/move is fun and all, but what they don't point out to you about it is that it prevents the base class operator= from being called when there's inheritance (because it's bypassing operator= entirely). i.e. it might be fine at the app-level since you might know all your callers in that case, but you shouldn't do it in a library that others might want to use, or your code will behave erratically.
