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?

"What will be the least work?" seems a relatively poor basis for making decisions. And it really isn't "quite a lot of work". Changing "Rank2Types" to "RankNTypes" is hardly any work at all. -Brent
