Hello,

This change makes things like:

  guix build --with-input=guile=guile-next guix -n --no-grafts

more useful and tractable.

Low-level rewrites are still possible for packages not marked
as hidden in 'commencement.scm', such as glibc:

  guix build --with-latest=glibc hello -n

Thoughts?

Ludo'.

Ludovic Courtès (2):
  packages: Use SRFI-71 instead of SRFI-11.
  packages: 'package-input-rewriting/spec' ignores hidden packages.

The primary motivation is to support things like:

  guix build guix --with-input=guile=guile-next

without triggering a rebuild of (@@ (gnu packages commencement)
guile-final) and similar things.

It is also consistent with package name resolution on the command line:
a package that cannot be named cannot be replaced.

* guix/packages.scm (package-input-rewriting/spec)[rewrite]: When P is
hidden, return it as-is.
* tests/packages.scm ("package-input-rewriting/spec, hidden package"):
New test.
* doc/guix.texi (Defining Package Variants): Update.
(Package Transformation Options): Update '--with-input' example.

Out of curiosity, what is the difference?  Aside SRFI-71 instead of
SRFI-11?  Or why do you prefer SRFI-71 over -11?

There’s no semantic difference, but SRFI-71 looks clearer, doesn’t it?
:-)

See
<https://lists.gnu.org/archive/html/guix-devel/2021-01/msg00234.html>
for the original proposal.
