regarded and expertly designed C++ library projects in the
world.

This is an older version of Boost and was released in 2015. The current version is 1.89.0.
boost::proto::functional::make_expr — A PolymorphicFunctionObject equivalent to the
proto::make_expr() function.
// In header: <boost/proto/make_expr.hpp> template<typename Tag, typename Domain = proto::deduce_domain> struct make_expr : proto::callable { // member classes/structs/unions template<typename This, typename... A> struct result<This(A...)> : proto::result_of::make_expr< Tag, Domain, A... > { }; // public member functions template<typename... A> typename proto::result_of::make_expr< Tag, Domain, A const... >::type const operator()(A const &...) const; };
In all cases, proto::functional::make_expr<Tag, Domain>()(a...)
is equivalent to proto::make_expr<Tag, Domain>(a...).
proto::functional::make_expr<Tag>()(a...) is equivalent to
proto::make_expr<Tag>(a...).
make_expr public member functionstemplate<typename... A> typename proto::result_of::make_expr< Tag, Domain, A const... >::type const operator()(A const &... a) const;
Construct an expression node with tag type Tag and in the
domain Domain.
