When I open ".py" file, the Python REPL is not started automatically,
when I open ".scm" file, the Geiser REPL should not be started
automatically, etc.  This is normal!  If you want to have such kind of
interactive programming, you need to start the REPL yourself.

No!  You want to break a normal behavior.  REPLs are not started
automatically when you open a file for editing.

Then running "C-x C-e" (geiser-eval-last-sexp) in .scm buffer should
give you the same impression, as it gives the same error if REPL is not
running.

This is normal, and I mean not only for Guix or for Geiser, but for
these kinds of interactive programming (using REPLs) in Emacs.

BTW I think this Geiser error is quite informative as it tells you what
to do.

The commands work in vanilla install!  All you need is "M-x run-geiser"
as the Geiser error tells.  But the documentation can always be improved
of course.

I think you are just not used to editing files using REPLs.  Did you
ever use Geiser or SLIME or other REPLs in Emacs before?
