Comment:

 This exact information already exists in ghc-exactprint -
 https://github.com/alanz/ghc-
 exactprint/blob/master/src/Language/Haskell/GHC/ExactPrint/Annotate.hs -
 and we tested it by running it on the whole of hackage.

 I agree that the comments are useless, any consumers should just use `ghc-
 exactprint` as it performs a lot of utility with the annotations. There
 haven't been many people who have used it though as the API is not great
 and balancing everything is quite complicated.
