Scheme Request for Implementation 202,
"Pattern-matching Variant of the and-let* Form that Supports Multiple
Values,"
by Panicz Maciej Godek,
has gone into FINAL status.

The document and an archive of the discussion are available at <https://srfi.schemers.org/srfi-202/>.

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 ability to pattern-match (or
"destructurally bind") the values of evaluated expressions (where the
match failure causes short-circuiting rather than raising an error)
and the ability to handle multiple values (where only the falsehood of
the first value causes short-circuiting).

Here is the commit summary since the most recent draft:

- Fixed a typo
- Follow format recommended by US Copyright Office.
- Copy edits. Editor's note.
- Drop trailing whitespace.
- Link to referenced SRFIs.
- Finalize.

Here are the diffs since the most recent draft:
