Evaluation Order and Precedence

Note that the constraint evaluates the sub-constraints left to right, meaning that Assert.That(i,Is.Null.Or.GreaterThan(9)); where i is a nullable int will work for both 12 and null. On the other hand, Assert.That(i, Is.GreaterThan(9).Or.Null); will only work for 12, but throw an exception for null, as null cannot be compared to 9.

The OrConstraint has precedence over the AndConstraint.
