I cannot imagine a viable implementation of things like =E2=80=98commit-clo= sure=E2=80=99 and =E2=80=98commit-relation=E2=80=99 from (guix git) done by shelling out = to =E2=80=98git=E2=80=99. I=E2=80=99m quite confident this would be slow and brittle. It looks like there=E2=80=99s no option other than carrying the two implementations. ~~~ Years ago, Andy Wingo sketched a plan for GNU hackers to implement Git in pure Scheme. That was on April 1st though, so people mistakenly assumed it was a joke and the project was never carried out. I digress, but I wonder: is there not even a viable Haskell or OCaml implementation of Git? Thanks, Ludo=E2=80=99.
