Struct template comma

boost::proto::comma — A metafunction for generating comma expression types, a grammar element for matching comma expressions, and a PrimitiveTransform that dispatches to the proto::pass_through<> transform.

Synopsis

template<typename T, typename U> 
struct comma :  proto::transform< comma<T, U> > {
  // types
  typedef proto::expr< proto::tag::comma, proto::list2< T, U > > type;           
  typedef type                                                   proto_base_expr;
  template<typename Expr, typename State, typename Data> 
  struct impl :  proto::pass_through<comma>::template impl<Expr, State, Data> {
  };
};
