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.
