Still trying to figure it out ... Also did the following check (OK) :

typedef set_type::accumulators_mpl_vector::type       wrapped_features;

typedef mpl::transform<
         wrapped_features,
         accumulators::detail::feature_tag<mpl::_1>
 >::type                                               features;

     BOOST_STATIC_ASSERT((
         mpl::equal_to<
             mpl::size_t<2>,
             mpl::size<features>::type
         >::value
     )); //OK

     typedef mpl::back<features>::type                   actual_back;

     BOOST_STATIC_ASSERT((
         is_same<b_type,actual_back>::value
     )); //OK
