Steven,

I really thank you. It works!

Just for anyone interested on this, here is the working solution (I
just put the important changes; the rest of the code is the same as
before):

    typedef mpl::vector< te::forward_iterator<_iter, const T&,
std::ptrdiff_t, T> > requirements;
    typedef te::any< requirements, _iter> fwd_iter_type;

Best,
