PS. opEquals issue is very annoying, indeed.
Yes, I forgot that you are allowed to overload via ref. That would make
sense for virtual functions.
The problem with allowing const ref rvalues is then you are not *able* to
make a better performing function, because rvalues match against const ref
as well as the non-ref version.
