How to generate fusion::vector from mpl::vector? How to generate
mpl::vector from fusion::vector?

BOOST_MPL_ASSERT((is_same<
                  fusion::vector<int, char>,
                  generate_fusion_vector<mpl::vector<int, char> >::type >));

BOOST_MPL_ASSERT((is_same<
                  mpl::vector<int, char>,
                  generate_mpl_vector<fusion::vector<int, char> >::type >));

I need generate_fusion_vector and generate_mpl_vector metafunctions. I
can write my own metafunctions, but i suspect that they already exist.

I generated fusion::map with help result_of::as_map before, so vector
generation is the same, but in current boost(trunk, 1.39 also) such
error occur:

D:\Libraries\boost_trunk\boost/fusion/sequence/intrinsic/size.hpp(56)
: error C2903: 'apply' : symbol is neither a class template nor a
function template
        D:\Libraries\boost_trunk\boost/fusion/container/vector/convert.hpp(23)
: see reference to class template instantiation
'boost::fusion::result_of::size' being compiled
        with
        [
            Sequence=boost::mpl::vector
        ]
        temp.cpp(71) : see reference to class template instantiation
'boost::fusion::result_of::as_vector' being compiled

I don't understand what is going on?
