Much welcome addition!

I would suggest running:

  guix shell -CP

(Currently ‘README’ suggests ‘guix shell’.)

The rationale is: it’s shorter, using a container avoids interference,
and ‘-P’ works well with ‘config.cache’ & co. (because the cached file
names then are $HOME/.guix-profile/…).

WDYT?

Thanks,
Ludo’.
