32 * {@code eval} operations are always equivalent. ie.<pre>
33 * boolean one = predicate.test(a);
34 * boolean two = predicate.test(a);
35 *
36 * assert one == two;

38 * <li>Equivalent input objects should map to equivalent output objects. ie.<pre>
39 * assert a.equals(b); // a and b are equivalent
40 *
41 * boolean x = predicate.test(a);
42 * boolean y = predicate.test(ab;
43 *
44 * assert x == y; // their test results should be the same.
45 * </pre></li>
46 * <li>The predicate should not modify the input object in any way that would
47 * change the evaluation.</li>
48 * <li>When used for aggregate operations upon many elements predicates
49 * should not assume that the {@code test} operation will be called upon
50 * elements in any specific order.</li>
