Please use ‘warning’ from (guix diagnostics) instead.

Does #f necessarily indicate a parse error?  Couldn’t we have more
detailed info about the error?  (Not a blocker but it would be nice.)

Nitpick: I’d suggest using a plain ‘if’ rather than ‘match’ in this case
since it’s a binary choice without destructuring.

Could you send an updated patch?

Thanks,
Ludo’.

Well if go through the changes, it could fail on each step of the let*,
so we could indeed be more precise, though it eventually comes down to
a fetch or parsing error. Will fix this in a later patch.

Actually I'm probably going to merge the different patches in a single
patch series, that would make it more convenient to review on your side.
