However, it appears to need, at least, the #includes:

#include <boost/shared_ptr.hpp>
#include <boost/mpl/vector.hpp>
#include <boost/preprocessor/cat.hpp>
#include <boost/preprocessor/iteration/local.hpp>
#include <boost/test/minimal.hpp>

Anything else?

Is this the variant static_visitor or the one from your
previous post:

  http://article.gmane.org/gmane.comp.lib.boost.user/65156

?

Is Layout a new namespace?  I don't see it in this post or the previous
one?

Thanks for any help, Paul.
