Hello Ludovic,

Apologies for late reply.  I thought how to reproduce it properly.

No,

--8<---------------cut here---------------start------------->8---
guix environment --ad-hoc aspell aspell-dict-ru coreutils -C -- aspell dicts
--8<---------------cut here---------------end--------------->8---

returns nothing, but need to return a list like

    en
    en-variant_0
    en-variant_1
    en-variant_2
    en-w_accents
    en-wo_accents
    en_AU
    en_AU-variant_0
    …

Thanks,
Oleg.
