I appreciate having a third opportunity.
This might be a lob-ball question, in a sense. I think over the years there's a certain cyclical reappearance of this idea that we should abandon flexible exchange rates and inflation targeting and move to some common North American currency or dollarization or fixed exchange rate. This idea was put about when the currency was very low. I just saw last week an argument to this effect put forward in The Globe and Mail. As I think you know, I've always favoured the status quo, and I wonder if you could explain why you believe that the flexible exchange rate and inflation targeting is better for Canada on economic grounds than some sort of North American common currency.
