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

boost::proto::default_generator — A simple generator that passes an expression through unchanged.
// In header: <boost/proto/generate.hpp> struct default_generator : proto::callable { // member classes/structs/unions template<typename This, typename Expr> struct result<This(Expr)> { // types typedef Expr type; }; // public member functions template<typename Expr> Expr operator()(Expr const &) const; };
Generators are intended for use as the first template parameter to the
proto::domain<>
class template and control if and how expressions within that domain are to be customized.
The proto::default_generator
makes no modifications to the
expressions passed to it.
