Auto Derive Haskell at Ashton Tobler blog

Auto Derive Haskell. In haskell 98, you can inherit instances of eq, ord, enum and bounded by deriving them, but for any other classes you have to write an explicit. To make this more robust, ghc has a notion of deriving strategies, which allow the user to explicitly request which approach to use when deriving an. There is a way around this which is to replace the imageid map in the definitions above by, imageid1, imageid2 for example, and then define a class. The class lift, unlike other derivable classes, lives in template. With deriveanyclass you can derive any other class. To address these issues, we propose an approach to specifying how to derive an instance of a class, together with new behavior for the deriving. This is to say that automatic deriving is baked into the haskell spec, and every compiler can choose to. Ghc extends this list with several more classes that may be automatically derived: Enable automatic deriving of instances for the lift typeclass for template haskell.
