Comment (by RyanGlScott):

 That sounds agreeable to me!

 Do you want to take a crack at fixing the users' guide? The relevant part
 of the codebase that you'd have to change is here:
 http://git.haskell.org/ghc.git/blob/9fd87ef8a16fbbce35205ae63d75d239bb575ccc:/docs/users_guide/glasgow_exts.rst#l3192
 And if you want to preview what your changes look like, you can either
 build just the docs (see
 [https://ghc.haskell.org/trac/ghc/wiki/Building/Docs#UsersGuide these
 instructions]), or you can fork GHC on GitHub and view a rendered version
 of `docs/users_guide/glasgow_exts.rst` directly (for example, see
 [https://github.com/ghc/ghc/blob/master/docs/users_guide/glasgow_exts.rst
 this]).
