//
//      where the given parameter should be an actor, which eval() function
//      returns a convertible type.

//
//      Lazy object construction
//
//      The set of construct_<> template classes and functions provide a way
//      of lazily constructing certain object from a arbitrary set of
//      actors during parsing.
//      The construct_ templates are (syntactically) used very much like
//      the well known C++ casts:
//
//          A a = construct_<A>(...arbitrary list of actors...);
//
//      where the given parameters are submitted as parameters to the
//      contructor of the object of type A. (This certainly implies, that
//      type A has a constructor with a fitting set of parameter types
//      defined.)
//
//      The maximum number of needed parameters is controlled through the
//      preprocessor constant PHOENIX_CONSTRUCT_LIMIT. Note though, that this
//      limit should not be greater than PHOENIX_LIMIT.
