In the page it is informed that sort has an average complexity of
O(nlog n), but I'm writing this:

  template <typename T, typename U>
  struct sort_hierarchy_pred : mpl::not_<
      boost::is_base_and_derived<T, U>

  typedef mpl::back_inserter< mpl::vector<> > aux_in;
  template <typename SequenceT>
  struct sort_hierarchies : public mpl::sort<SequenceT,
      typename mpl::lambda<sort_hierarchy_pred<mpl::_, mpl::_> >::type
      , aux_in>

and for a sequence of 5 or more, the compile time and memory usage
gets too huge. To became unuseable.

What I'm trying to achieve is a sequence of types that are sorted with
the bases first...
Could anybody shed some light why and if there's some workaround this?

thanks in advance,
