Thanks for updating the Cabal file. The reason I commented out the
Data.HList.TypeEqO was because I couldn't find it. I grepped the HList
source tree for it and I found references to it only in the following
./examples/MainGhcGeneric1.hs: module Data.HList.TypeEqO,
I couldn't find it on Hoogle or Hayoo either. Am I missing something?
