- So when we said that haskell is good for abstraction, what did we actually mean? Do we have something like java generics or C++ templates?

- Even better! Haskell supports polymorphism for both data types and functions.\\
- Let's start with a polymorphic data type:
- \begin{haskellcode}
- data List t = Empty | Cons t (List t)
- \end{haskellcode}
- So we just implemented our own singly-linked List. For any type! Let's use it:
- \pause
- \begin{haskellcode}
- intList :: List Int
- intList = Cons 3 (Cons 5 (Cons 2 Empty))
-
- charList :: List Char
- charList = Cons 'x' (Cons 'y' (Cons 'z' Empty))
-
- -- whatever you can imagine goes here
- \end{haskellcode}
