// agurt, 25/apr/04: technically, the ADL workaround is only needed for GCC,
// but putting everything expect public, user-specializable metafunctions into
// a separate global namespace has a nice side effect of reducing the length 
// of template instantiation symbols, so we apply the workaround on all 
// platforms that can handle it
