I've defined some custom tag for user specific function like :
struct conj_tag {};

I have made the following expression builder using make_expr :

template<class X>
typename proto::result_of::make_expr< conj_tag, X const &>::type
conj( X const& x )
{
  return proto::make_expr<conj_tag>(boost::cref(x));
}

And I match this function using the following grammar rule :
struct my_grammar : or_< // some terminal
                                           , bp::function< 
bp::terminal<conj_tag>, my_grammar>
                                          > {};

Now, how should I overload operator() of a callable_context to match 
this special tag ?
Thanks in advance
