@Jon: This is better in the case where you do get an rvalue, and the default
guidance to “pass by value then move as needed” doesn’t apply just to smart
pointers but to any type that’s cheaper to move than copy. And yes, my opinion
has changed. Basically that came from paranoia about a different optimiz... | |

Why are we making pointers even more complicated to teach and learn? Somehow
we have figured out a way to make this more difficult to properly teach in a
consistent manner and this makes learning exponentially harder.
