Great! Thanks a lot.
BTW, another two small remarks: The "variant::types" typedef that was
used here is not documented, and it will be helpful if I could read
about it and about its possible usages. And if you wish not to burden
the users with mpl, then it's possible to wrap mpl::contains in a
constant boolean value "can_be", as I suggested.
But anyway, thanks again.
