Comment(by steven_watanabe):

 Actually, I think it would be better if fusion::push_back were overloaded
 to allow either const or non-const arguments, like

 {{{
     template <typename Sequence, typename T>
     inline typename result_of::push_back<Sequence, T>::type
     push_back(Sequence & seq, T const& x);

     template <typename Sequence, typename T>
     inline typename result_of::push_back<Sequence const, T>::type
     push_back(Sequence const& seq, T const& x);
 }}}

 Regardless, result_of::push_back ought to work correctly for non-const
 arguments.  If push_back always adds const, then so should
 result_of::push_back.
