Hi,

Thanks for your feedback.

No answer to your questions means “I do not know” or “Something is indeed
missing on Guix side”.

use-modules is from Guile
https://www.gnu.org/software/guile/manual/guile.html#Using-the-Guile-Module-System

The others are Guix specific.

I do not understand this question but I guess it is because the question
#2.

Nothing I am aware.

Example:

    (use-modules (guix)
                 (gnu packages base))

loads the modules named (guix) and named (gnu packages base).  See #2.

Since all the packages are defined in modules (gnu packages FOO) then it
is very common to write (gnu packages emacs-xyz) or (gnu packages
bioconductor) or etc. then ’use-package-modules’ provides a shortcut;
other said,

    (use-package-modules emacs-xyz bioconductor)

is equivalent to:

    (use-modules (gnu packages emacs-xyz)
                 (gnu packages bioconductor))

Thanks for your effort and perseverance!  Your feedback is very valuable
and I hope that it could help in improving the manual by connecting some
missing dots.
