+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!
