Hi Ford, Haskell does support ad-hoc polymorphism via type classes. In short, class Foo a where -- type declarations for related sets of functions that are polymorphic in a go here instance Foo Int where -- function definitions with a specialized to Int go here. The Show class is probably a fairly simple example you can play with in ghci. data Test = Test instance Show Test where -- show :: Test -> String show t = "Hello World" Thanks, Arjun On Wed, Jul 6, 2016 at 12:05 PM OxFord <fordforox@gmail.com> wrote:

Hello,

why does haskell support only parametric polymorphism?

Is it because ad hoc p. || multiple dispatch is bad in general?

King Regards,
