This module implements the binding forms for multiple values
let-values and let*-values. These forms are similar to
let and let* (see Local Variable Bindings), but they support
binding of the values returned by multiple-valued expressions.
Write (use-modules (srfi srfi-11)) to make the bindings
available.
(let-values (((x y) (values 1 2))
((z f) (values 3 4)))
(+ x y z f))

let-values performs all bindings simultaneously, which means that
no expression in the binding clauses may refer to variables bound in the
same clause list. let*-values, on the other hand, performs the
bindings sequentially, just like let* does for single-valued
expressions.
