[Boost-users] [Accumulators] Matching via ADL.

Subject: [Boost-users] [Accumulators] Matching via ADL.

In this code sequence:

boost::accumulators::accumulator_set<
  long,
  boost::accumulators::features<
    boost::accumulators::tag::sum > > my_acc;

long f( )
{
  using namespace boost::accumulators;
  return sum( my_acc );
}

why do I need a using declaration? Shouldn't sum() be found
via ADL?

Using Boost 1.39 & MSVC 8.

Thanks
