6.4.10 SRFI-11 - let-values

This module implements the binding forms for multiple values let-values and let*-values. These forms are similar to let and let* (see Local 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.
