It absolutely does. Here is a (modified) snippet of my Java code from yesterday.

    final boolean hasUncollectedSecret =
       switch (each)
       {
               
          case Wall()    -> false;
          case Goal()    -> false;
          case Player p  -> false;
          case BasicCell(Underneath(_, var collectible), _)
             ->
                switch (collectible)
                {
                        
                   case NONE, KEY -> false;
                   case SECRET -> true;
                        
                };
          case Lock()    -> false;
               
       };
