boost::proto::transforms_type — 
          The type used to define the global proto::transforms,
          a key for use when creating and accessing a slot in a transform environment for
          a set of external transforms.
        
// In header: <boost/proto/transform/when.hpp> struct transforms_type { // public member functions template<typename Value> env<transforms_type,see-below> operator=(Value &) const; template<typename Value> env<transforms_type,see-below> operator=(Value const &) const; };
            The proto::transforms_type type, along with the proto::transforms
            global, are declared using the BOOST_PROTO_DEFINE_ENV_VAR() macro.
          
transforms_type public member functionstemplate<typename Value> env<transforms_type,see-below> operator=(Value & value) const; template<typename Value> env<transforms_type,see-below> operator=(Value const & value) const;
                If Value is a specialization boost::reference_wrapper<T>,
                this function returns env<transforms_type, T &>(value.get()).
              
                Else, if the type Value is non-copyable (i.e., a function, an array, abstract, or an ostream),
                this function returns env<transforms_type, Value ,
                where cv &>(value)cvconst for the second overload, and empty
                for the first.
              
                Otherwise, this function returns env<transforms_type, Value>(value).
