Hi Ricardo,

Thanks for the update, looks great!

I originally sent this patch because I needed pandoc 2.9.* at some
point, but I no longer use it (at least for now) and I'm no Haskeller so
my motivation is a bit low to be honest :D

If no one else gets to it, I may give this a shot in a while (don't hold
your breat) :p

I suggest you let know guix-devel, hopefully someone will chime in!
