 The Haddock documentation for `Ix`
 [http://hackage.haskell.org/package/base-4.7.0.2/docs/Data-Ix.html here]
 says that the minimal definition requires `range`, `index`, and `inRange`.
 But then it says that the minimal definition requires `range` and
 `inRange`. It seems that Haddock is inferring a `MINIMAL` definition where
 none is in the code. Perhaps a `MINIMAL` should be added.
