Right.

Hmm... does that mean that the current code doesn't actually use the
finalizers yet?

Your choice.

The question is only whether it would work.

But `iter-yield' is still (lexically) in the body of the calling
function, passed as a callback to some new higher-order function.

I guess another way to ask the same question is to ask if things like

    (mapcar (lambda (x) (iter-yield x)) list)

can be used.
