Sure, but this definition leaks space, which I think is one of the
points that Reiner made.

The Stream datatype seems to be much better suited to representing loops than the list datatype is. So, instead of programming with the lists, why don't we just use the Stream datatype directly?
I think the main reason is that streams don't store data and therefore don't support sharing. That is, in
let xs = map f ys in (sum xs, product xs)
the elements of xs will be computed once if it is a list but twice if it is a stream.
