boost::proto::lazy::impl
// In header: <boost/proto/transform/lazy.hpp>
template<typename Expr, typename State, typename Data>
struct impl : proto::transform_impl<Expr, State, Data> {

types
typedef see-below result_type;
proto::lazy<T>::impl<Expr,State,Data>::result_type
is calculated as follows:
If T if of the form
O(A0,...An), then let O'
be boost::result_of<proto::make<O>(Expr, State, Data)>::type
and let T' be O'(A0,...An).
Otherwise, let T'
be boost::result_of<proto::make<T>(Expr, State, Data)>::type.
The result type is
boost::result_of<proto::call<T'>(Expr, State, Data)>::type
.
