        .single.newInstance(const Symbol(""), ["Her majesty's theater"]);
      
      MethodMirror scene = annotatedDeclarations(Scene, on: play.runtimeType)
      .where((decl) => decl.annotation.act == "III" &&
                      decl.annotation.scene == "I")
      .single;
      
      perform(play.getField(scene.simpleName).reflectee);
