   [partial-order](https://hackage.haskell.org/package/partial-order).
 Differences include:
 * PartialOrd has a comparison valued in Maybe Ordering; we use a fresh
-  type with four constructors.
+  type.
 * Where types have several natural partial orderings, we provide
   newtypes rather than choosing one.
-* We pay slightly more attention to algorithmic complexity.
