Thanks for the reply. Would it be possible to fit sparse matrices in this as
well (specializing matrix_storage)? I've got another question regarding the
traits, why 

template< typename T >
some_traits<T>: some_detail_traits<T, metafunc<T> > {
};

with

template< typename T, typename S >
some_detail_traits {
    T identifier_type;
    S some_type;
};

instead of 

template< typename T >
some_traits<T> {
    typedef T identifier_type;
    typedef typename metafunc<T> some_type;
};

?   (and wouldn't boost::remove_cv be a better choice than
boost::remove_const?)

Thanks,

Rutger
