Is there any advantage to doing:
// An if_ "operator" template<typename Expr> typename boost::proto::result_of::make_expr< boost::proto::tag::function, Domain, keyword::if_, Expr>::type if_(Expr const &expr) { return boost::proto::make_expr<boost::proto::tag::function, Domain>( keyword::if_(), expr); }
over:
typedef Wrapper<boost::proto::terminal<keyword::if_>::type> IfTerminal;
// An if_ "operator." namespace { const IfTerminal if_ = {{}}; }
and letting proto take care of creating the function expression? Perhaps the former has one or two less template instantiations but the latter is certainly easier to maintain
I can't find lu right now but i made an extensive test for this and the function form id more scalable in terme of compile time and exe size
