deriveMeta :: Name -> Q [Dec]Source
Given the type and the name (as string) for the type to derive,
generate the Data instance, the Constructor instances, and the Selector
instances.
deriveData :: Name -> Q [Dec]Source
Given a datatype name, derive a datatype and instance of class Datatype.
deriveConstructors :: Name -> Q [Dec]Source
Given a datatype name, derive datatypes and
instances of class Constructor.
