What about:

   function "&" (Left, Right : String) return String_Sequence is
   begin
      return (new String'(Left), new String'(Right));
   end "&";

   function "&" (Left : String; Right : String_Sequence)
      return String_Sequence is
   begin
      return String_Sequence'(1 => new String'(Left)) & Right;
   end "&";

   Colors : constant String_Sequence := "red" & "orange" & "dark green";
