Constructors Same Both arguments are the same. SameHead d The arguments are recursive expressions of the same form, but their subterms differ. Return a "decorated" term that shows where the differences are Differ d d The arguments differ and are not of similar form (don't recurse) DontCare Instances Functor DiffResult Typeable1 DiffResult Pretty F0Diff Pretty T0Diff Eq d => Eq (DiffResult d) Data d => Data (DiffResult d) Ord d => Ord (DiffResult d) Read d => Read (DiffResult d) Show d => Show (DiffResult d)
