A char[S] buffer to store and retrieve objects.
Sort of a variant, but does not keep track of the nature of the stored data, since that knowledge is available via the current state.

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 ().
