You have seen how parametric polymorphism and higher-order functions help in the process of abstraction. In this chapter, I’ll introduce a new kind of polymorphism that sits in between parametric and the absence of polymorphism: ad hoc polymorphism. Using this feature, you can express that certain types exhibit a common behavior. Incidentally, you will also learn how Haskell makes it possible to use addition, (+), on different numeric types like Integer and Float while maintaining a strong type ...
