The review of Joel de Guzman's Fusion library begins today, May 1, 2006, and continues through May 10, 2006.

In boost/fusion/tuple/tuple.hpp there's this: get(Tuple& tup) { typedef result_of::at_c<Tuple, N> at_meta; return extension::at_impl <typename traits::tag_of<Tuple>::type >::template apply<Tuple, mpl::int_<N> >::call(tup); } I don't see any use of the at_meta typedef. What's the purpose of this typedef? TIA.
