I'm not only not talking about such a thing, I don't even understand it.
What I meant was this: trivially any procedure that returns multiple
values could as well return a single value which is an aggregate
of some sort such as a list or general vector.  However, it costs
something to aggregate and disaggregate this value, a cost which *some*
implementations of multiple values need not pay.
