It is possible to collect statistics about what kind of test data that has been generated during property evaluation. This is useful if you want to inspect the test case distribution, and make sure your property tests all different kinds of cases, not just trivial ones.
For example, you might have a method that operates on lists, and which behaves differently if the list is sorted or not. Then it is crucial to know if ScalaCheck tests the method with both sorted and unsorted lists. Let us first define an ordered method to help us state the property.
