make no mention that X should have a nested type typedef. IOW, X must be a metafunction as defined here:
http://www.boost.org/libs/mpl/doc/refmanual/metafunction.html
However, I believe it should since I'm getting compile-time error messages without the nested typedef.
The tuple_methods_proto.cpp in <boost-vauilt>/Template Metaprogramming demonstates the problem.
