Hello world example in Boost accumulator reference manual does not compile

[jeadorf@…]

In the code example http://www.boost.org/doc/libs/1_54_0/doc/html/accumulators/user_s_guide.html#accumulators.user_s_guide.hello__world_

    std::cout << "Moment: " << accumulators::moment<2>(acc) << std::endl;

should be

    std::cout << "Moment: " << moment<2>(acc) << std::endl;
