Properly use the "Std Swap Two Step".
I hate this. Why it isn't intuitive like proposed in here? http://ericniebler.com/2014/10/21/customization-point-design-in-c11-and-beyond/

Because prefixing with
std::
shrinks the scope of ADL in such a way that custom (better)swap
implementations are not found. It's a nuance, yes, but I don't think we'll see it out of the language any time soon.65a2e56

Yeah, it would be nice if they said that since C++17 one can write just
std::swap(a, b)
and the generic implementation will finally do the argument-dependent lookup voodoo on its own.65a2e56
