Local variable example placeholders

i.e

    public void MyTest
    {
        int exampleVal = 0;
        this.Given(_ => GivenAn(exampleVal)
            .WithExamples(new ExampleTable("Example Val") { 1, 2, 3 }))
            .BDDfy();
    }

The local `exampleVal` variable will be set for each example. Must say, pretty happy with this :P
