Works fine for me:

     ScreenElement[][] layer_map;
     foreach(ScreenElement[] single_layer; layer_map)	// you may drop [][]  
as they are not needed
     {
         foreach(ScreenElement element; single_layer)    // did you have  
had a typo here? , -> ;
         {
             element.display();
         }
     }
