[boost] [mpl] at<> example bug?

Looks like the example found here: http://www.boost.org/doc/libs/1_54_0/libs/mpl/doc/refmanual/at.html is buggy: BOOST_MPL_ASSERT_RELATION( (at< range, int_<0> >::value), ==, 10 ); It should be: BOOST_MPL_ASSERT_RELATION( (at< range, int_<0> >::type::value), ==, 10 ); Mostafa
