 Replying to [comment:12 mpickering]:
 > Is it possible to derive these instances using GHC.Generics?

 I believe so, although with `GHC.Generics` you cannot have special cases
 for unlifted types like `Int#` (currently, the Phab differential uses the
 [http://hackage.haskell.org/package/template-haskell-2.10.0.0/docs
 /Language-Haskell-TH-Syntax.html#t:Lit Lit] type from `template-haskell`
 to deal with them).
