I'm fine with making the changes to cabal, but before I do, I want to
make sure that we really want to do this. I did a quick investigation
of how many modules need to be updated on Hackage. It's about 775.
That will require quite a lot of work by quite a lot of people. Could
we instead have Rank2Types be an alias for RankNTypes?

Cheers,
Johan
