Thanks, sorry I missed your IRC response. I'm not familiar with
sneek. Can you provide a reference?

I was thinking autodoc might help me understand guix/guile. No?

I am trying to get all the bells and whistles working. In search of a
more perfect setup, I switched back to GuixSD, so comments below relate
to GuixSD. Now, when I 'M-x guix-edit RET screen' & 'M-x run-geiser' I
get auto doc works and I see these buffers:

 MR Name                    Size Mode             Filename/Process
  -- ----                    ---- ----             ----------------
 *  * Guile REPL *           635 REPL             (Guile REPL<1> run)
 *  *Guix REPL*              312 REPL             (Guile REPL run)
 *  *Guix Internal ...       312 REPL             (*Guix Internal REPL*

Can you comment on whom/what each of these REPLs is used by/for?

If I want to use a REPL, which one should I use?

Would it make sense to add this info to the doc?

OK, but I am going in the other direction, trying to get '8.3 The
Perfect Setup' working. Right now, unless I manually start the 3rd REPL,
these commands: ‘C-c . u’ ‘C-c . b’, ‘C-c . s’, ‘C-c . l’, all produce
'or: Geiser REPL not found' in *Messages*.

Is this normal?

If so, would it be a helpful enhancement if guix-emacs started the 3rd
REPL automatically?
