This is confusing, I should fix it (sometimes...).

This form was an experiment with another way to define multiple
bindings.  It may be confusing -- but only the top-level is a problem,
since in a module context you cannot redefine `values' anyway.
(Judging by the `(define a (+ a 1000))', you seem to be attached to
the top-level behavior...)
