I always thought T&& made sense as a movable reference. In order to move something, you need to change where the reference points, so conceptually you need a reference to the original reference to update it. (Effectively a double reference)

I will say, you can’t beat the satisfaction of tracking down the root cause and actually fixing the bug. I don’t understand why so many people meme about covering up bugs with crazy hacks. It’s not fun constantly looking over your shoulder to see if that bug has resurfaced. They start to pile up.
