I'm still at the point of not trusting copy-on-write yet, but I think
you're misinterpreting your results. If I'm understanding the way in
which LC has implemented copy-on-write, then whether or not you use
references in parameters, the "return p-1" code will have to make a copy
on the stack to return a value - you can't just return a reference. So
all you're changing by removing the "@" is one level of copying.
Of course, I may well be not quite understanding what's been
implemented, in which case I welcome any correction.
