1= Quicksort in Haskell
2The first thing to know about Haskell's syntax is that parentheses
3are used for grouping, and not for function application.
4
5```haskell
6quicksort :: Ord a => [a] -> [a]
7quicksort [] = []
8quicksort (p:xs) = (quicksort lesser) ++ [p] ++ (quicksort greater)
9 where
10 lesser = filter (< p) xs
11 greater = filter (>= p) xs
12```

14The parentheses indicate the grouping of operands on the
15right-hand side of equations.
