Hi, I'm trying to troubleshoot some bugs in the venerable emacs-guix packag=
e, which you've probably heard of. In its default configuration, emacs-guix=
uses geiser to set up one Guile REPL (*Guix REPL*) to handle various guix =
operations, and tells it to --listen on a domain socket; and then it uses s=
ome comint functions to connect to the domain socket, to provide another Gu=
ile REPL (*Guix Internal REPL*) which it uses for various other guix operat=
ions while the main REPL is busy.
In guix bug#73462, I figured out that the bug was caused by, for some unkno=
wn reason, (guix gexp) reader syntax was working in the main REPL (*Guix RE=
PL*) but not in the REPL that was over the socket (*Guix Internal REPL*). A=
work around is available, which is to run an extra ",re (guix gexp)" in th=
e internal REPL buffer, and then after that it works fine, but I don't unde=
rstand why that should be necessary. Can somebody help me figure if this is=
some kind of bug in Guile, or a different issue...?
This can be reproduced this one my system command line with the following c=
ommands. Of course, you would need to adjust for your own paths. On one ter=
minal:
``` shell
christopher@theoden ~$ /gnu/store/g1fhmjs2mh8a0djfnyaha49ihb5cmkas-profile/=
bin/guile --no-auto-compile -L /home/christopher/Repos/emacs-guix/scheme -C=
/home/christopher/Repos/emacs-guix/scheme -L /home/christopher/.config/gui=
x/current/share/guile/site/3.0 -C /home/christopher/.config/guix/current/li=
b/guile/3.0/site-ccache --listen=3D/tmp/test-socket
```
Then on another terminal:
```shell
christopher@theoden /gnu/store/pg7s74p1p3bf2k848xy4j0x8dcqv248l-netcat-open=
bsd-1.219-1/bin$ ./nc -U /tmp/test-socket

scheme@(guile-user)> ,m (emacs-guix)
scheme@(emacs-guix)> (guix-command "pull")
Updating channel 'guix' from Git repository at 'https://git.savannah.gnu.or=
g/git/guix.git'...
Building from this channel:
guix https://git.savannah.gnu.org/git/guix.git 8a7bd21
ice-9/boot-9.scm:1685:16: In procedure raise-exception:

lf.scm:84:18: Unknown # object: "#~"
```
But the same command, which is (guix-command "pull") works fine in the firs=
t terminal.
Some system information:
``` guix describe

```
``` guile --version
guile (GNU Guile) 3.0.9
```
Regarding the sockets issue, there is another bug I have found related to t=
he use of the socket based REPL, described in bug#74250, but that one is mo=
re difficult to point to a specific cause or try to blame on Guile.
