Can a user define a derivable type class of her own? If yes, how?
GHC has a feature which lets you define classes such that making an instance of them is as easy as deriving. It's called Generic classes. See GHC's documentation for the details: http://www.haskell.org/ghc/docs/latest/html/users_guide/generic-classes.html Hth, Josef
