Add missing pragma: LANGUAGE RankNTypes #46

What version of ghc are you using? I don't this compiler error on ghc-7.4.1. I'll go ahead and merge this anyway.

I'm running GHC 7.6.3 here. I'm surprised that your version doesn't complain about the missing pragma. Could it be that in your setup you are passing the -XRankNTypes parameter to GHC somehow?

No. I don't get the errors when compiling using cabal, ghc alone, or loading the module into ghci. Either way, it looks like we need the pragma.
