There have been discussions about having a raco importer (for the =E2=80=9Cguix import=E2=80=9D command), but I think the effort stalled. It= =E2=80=99d go a long way bringing the Racket/Guix/Guile communities together, and it can be hacked in a language all three communities love. :-) Thanks for your work! Ludo=E2=80=99.
