Comment(by guest):

 I attached a patch to add DeriveFunctor, DeriveFoldable, and
 DeriveTraversable, but I don't know if I did everything necessary to add
 the extensions.  In particular, the notes in Language.Haskell.Extension.hs
 say that new extensions should be added to the lists in
 Distribution.Simple.X.languageExtensions, but (at least for GHC) that
 seems to be generated dynamically.
