Hi,

I'm getting this error on trunk

../../../boost/accumulators/framework/extractor.hpp:36:74: error: no 
type named 'result_type' in 'boost::fusion::void_'
         typedef typename mpl::apply<AccumulatorSet, 
feature_type>::type::result_type type;
                 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~

I'm including
#include <boost/accumulators/framework/accumulator_set.hpp>
#include <boost/accumulators/statistics/count.hpp>

If I add the following include everything is OK.

#include <boost/accumulators/accumulators.hpp>

Is this a know issue?

Best,
Vicente
