Thank you for taking a closer look! Sorry I did not get back to you on
the system-path question before. Of course, you were right.

If you will please accept an excuse for my tardiness: My family has a
new sister. Time passes when a baby cries.

I regularly notice missing imports, too, but haven't figured out when
they present an obstacle to running a Guile program.

Thanks for doing that! Now you and I are co-conspirators in re-arranging
the procedures.

Thank you for finding those. I have poor vision and am not good with
details, including speling.

Yes, I will read the GNU ChangeLog spec one more time, but all hope may
be lost.

My commit messages are widely regarded as wordy, roundabout and overly
documentative.

I use 'guix deploy' and will test your patch series shortly. (Despite
the previous shortcomings, I have been using it in production.) My
branch rebase is overdue.

Unfortunately, I have many custom patches, including some affecting core
packages. A branch rebase locally causes a full bootstrap and takes
about two days.

Given your attention here, I am sure your changes are fine. Folks should
feel free to merge your work before I return with confirmation. Thanks!

Kind regards
Felix
