OK.

I choked for a few hours on this one, my main problem being that I
didn’t want us to duplicate the logic from build-system/python.scm.
This led to commits f37f2b83fa95c1fe2bf01c4b8072cfc23d4c67ec and
1618006d0bc9bfdc63f4d199fd980f29ecc78ec4.

Is the “variant” property really needed?  In Python it’s needed because
the 2.x variants sometimes need a different set of dependencies that
‘package-with-python2’ cannot automatically guess.  Conversely,
‘package-with-guile-2.0’ has no need for that.

If the variant is not needed, then I recommend using
‘package-with-input-rewriting’.

If the variant is needed, then could you use ‘package-mapping’ as in
1618006d0bc9bfdc63f4d199fd980f29ecc78ec4?

Could you add comments explaining why camlp4 needs to be propagated and
 why #:make-flags is removed?

Maybe add a different synopsis?

Apologies for taking so long!

Thanks,
