Thank you for the fix. I can confirm (using the original reproducer) that it
works when run from guix repl:
$ GUILE_AUTO_COMPILE=0 guix repl -qL .
GNU Guile 3.0.9

Enter `,help' for help.
scheme@(guix-user)> ,use (xx)
;;; ((xx))
However there seem to be few more edge cases that are still not working.
Dot multiple times:
$ GUILE_AUTO_COMPILE=0 guix repl -qL ././.

;;; ((#{.}# #{.}# xx))
Double-dot:
$ GUILE_AUTO_COMPILE=0 guix repl -qL ../tmp

scheme@(guix-user)> ,use (xx)
;;; ((.. tmp xx))
Should I report those as separate bugs? Or do you think I should just re-open
this one?
Side-note: I have to say I am confused about behavior of guix repl with
/dev/stdin. Everything seems to work there:
$ echo '(use-modules (xx))' | GUILE_AUTO_COMPILE=0 guix repl -L . /dev/stdin
;;; ((xx))
$ echo '(use-modules (xx))' | GUILE_AUTO_COMPILE=0 guix repl -L ././.
/dev/stdin
;;; ((xx))
$ echo '(use-modules (xx))' | GUILE_AUTO_COMPILE=0 guix repl -L ../tmp
/dev/stdin
;;; ((xx))
I have no idea why. I would also try -c as I did in my original reproduces, but
guix repl does not support it (I wonder why).
For completeness' sake I am including original message I wrote before trying
`guix repl' and therefore writing the above text instead:
However I am unsure whether it works. I pulled the Guix channel:
$ guix describe
Generation 1 Jul 18 2024 18:44:20 (current)
guix e3dfed5
repository URL: https://git.savannah.gnu.org/git/guix.git
branch: master
commit: e3dfed59d39ac60dd2e2b9ef9f4ef63a2a081f41
As far as I can tell that commit should include your fix (or even better, that
commit is your fix). However when I try the reproducer from the original bug
report, I am still getting:
$ GUILE_AUTO_COMPILE=0 guile -L . -c '(use-modules (xx))'
;;; ((#{.}# xx))
