Swap the content with other, of same type.
Both variants must be built beforehand, because swapping the actual data requires reading it (with as()), and this is not possible on unconstructed variants: it would require some dynamic testing, which should not be the variant's responsability. Swapping between built and (possibly) non-built is done with variant::move ().
