Here's the abstract:

The SRFI-2 library introduced the and-let* form for short-circuited evaluation in the style of the and form with the ability to capture the (non-#f) results in the style of the let* form. This document extends the and-let* form with the abilities to pattern-match (or "destructurally bind") the values of evaluated expressions (where the match failure causes short-circuiting, rather than raising an error), and to handle multiple values (where only the falsehood of the first value causes short-circuiting).

Regards,


SRFI Editor
