I asked on guix-devel to see if anybody was interested in an Haskell
update; I just attached a WIP patch to see if anyone would be interested
in helping out, since I didn’t really know where to start.  Sending it
to guix-patches would make it more likely to be forgotten since it
is a higher-volume list.

Now that more people have showed interest, I recently sent a patch for
it to guix-patches[1].  I still have to address some failing tests
before it’s ready to merge.  :)
