This is one of the main motivation of Francis Glassborrow's
proposal to introduce explicit defaults, i.e. let people say
explicitly that they want the implicitly generated usual suspects
without having to actually write them. That has the potential
of solving the ABI changing and performance hurting issue I
raised a couple of weeks ago. It would also save me from going
on a croisade to ban C++ textbooks that promote rigid rules
and compilers that implement them ;-)
