WebThe category Hask of Haskell has data types as its objects. The morphisms f : T → U are simply given by function, i.e. programs, of the speciﬁed types, e.g. showSquare :: Int -> String showSquare x = show (x*x) 2 is a morphism between Int and String. WebThis assumes you are familiar with Haskell and basic category theory. Categories We have a abstract category C which consists of objects and morphisms. Objects : Morphisms : → For each object there is an identity morphism id and a composition rule ( ∘) for combining morphisms associatively.
