Is it really only a matter of inclsion of rule<>'s into some container?
I'm not completly sure. If yes, your 2nd suggestion is the better one,
because it's less intrusive and because it don't add features to the
rule<>'s template, which aren't used very often. But if there are other
situations, where copy sematics are required, the first suggestion may
be preferable.
