Let's check on a few very common list operations:
\setHaskellCodeStyle
\begin{lstlisting}
> [1, 2] ++ [4, 5] -- append two lists
> head [1, 2, 3] -- first element
> tail [1, 2, 3] -- everything after the head
> reverse [1, 2, 3] -- reverse a list
> take 2 [1, 2, 3] -- take the first two elements
> drop 2 [1, 2, 3] -- drop the first two elements
> sum [1, 2, 3]
> elem 7 [1, 2, 3] -- is there a 7 in the list?
\end{lstlisting}

A String in haskell is just a list of Chars!
