Oops, I meant "for D of Period", i.e.

   for D : Ada.Calendar.Time of Period loop
      ...

but you'd need

   function Constant_Reference
     (Container : aliased Date_Container;
      Position  : Cursor) return Constant_Reference_Type;

returning

   type Constant_Reference_Type
      (Element : not null access constant Ada.Calendar.Time) is private
   with
      Implicit_Dereference => Element;

which is clearly meant for actual containers and here would require - I
think - allocating an Ada.Calendar.Time, and of course freeing it
eventually.

Shame, it makes it tricky to support lazy evaluation. But perhaps we
shouldn't want to ...
