[boost] Re: [MPL] Type detection

Ok, now I want to create an mpl::vector of std::vectors,
instantiated over the types in my sequence.  I think this
is what I want, but I want to make sure it's the best way:

template <typename T>
struct make_vector
{
    typedef std::vector<T> type;
};

template <typename T>
struct foo
{
    typedef typename as_sequence<T>::type seq;
    typedef typename transform<seq, make_vector<_1> >::type my_vec;

    tuple<elements_of_my_vec> v;
};

foo f;

get<3>(f.v);

Obviously, my problem is making a tuple from an mpl::vector.
I sure hope this is possible and easy, because it would totally
rock if it is.
