I thought we were agreed that there was no way to achieve the goals (of decoupling) without the multiple instantiations. In any case, I believe that is so, and I suppose I am trying to convince people that it's (very much!) the lesser of two evils to have the multiple instantiations and the decoupling. I really think this is a case where the apparently easier way is in fact the harder one. -- Best wishes, Nick Roberts
