I know about that example. I was interested in how I can use that
phoenix::accumulate when iterating over my _prob? In essence how can I
rewrite the following code to use phoenix's version of accumulate?

   std::vector< point > d;

   double sum_prob = std::accumulate( d.begin()
                                    , d.end()
                                    , 0.0
                                    , bind( &point::_prob, arg2 )
                                    );

Thanks,
Christian
