You missed the point :-)
Serialize is a general entry point, which dispatches to Write. If you call it again from Write, it will redispatch
to Write, hence the loop.
Now do you think that Write of B is really Serialize of A, plus something else?
Isn't it *Write* of A, plus something else? If you change your package to
package body B is
procedure Write(
This : in Object ) is
begin
A.Write( A.Object( This ) );
Put_Line( "Q =" & Natural'Image(This.Q));
end Write;
end B;
It will be OK.
Oh, by the way, why do you need Serialize at all? Since all it does is call Write, why don't you
call Write directly?
