Assert.Throws with NHamcrest

NHamcrest is a C# port of Hamcrest, a popular matching library. I recently added support for Assert.Throws:

    [Test]
    public void Throws()
    {
        Assert.That(() => { throw new ArgumentNullException(); }, 
            Throws.An<ArgumentNullException>());

        // with a predicate
        Assert.That(() => 
            { 
                throw new ArgumentNullException("message", new Exception()); 
            }, Throws.An<ArgumentNullException>()
            .With(e => e.Message == "message" && e.InnerException.GetType() == typeof(Exception)));
    }
