Documenting what can be derived 'out of the box' by GHC's "deriving"
Nowhere in the documentation is it clearly stated which classes can be derived (assuming extensions as necessary) by GHC's "deriving" mechanism. As determined by reading the sources, this appears to be
- Bounded, Enum, Eq, Ix, Ord, Read, Show, Functor, Foldable, Traversable, Generic, Generic1, Data, Lift.
This was discussed on haskell-cafe -- see https://mail.haskell.org/pipermail/haskell-cafe/2016-October/125379.html.
PS: I would be willing to fix this myself, if only I knew *where* to insert that information so that it is easily findable!
