Fill generic type parameters from types in examples

E.g.

[Scenario]
[Example(typeof(RedWidget))]
[Example(typeof(BlueWidget))]
public static void MungingWidgets<TWidget>(TWidget widget)
    where TWidget: IWidget, new()
{
    "Given a {0}"
        .f(() => widget = new TWidget());

    "When I..."
        ....
}

Need to think of another way to do it. The example shown would close the method with the type parameter being System.Type and will always do so unless we special case System.Type, which is just ugly.

We could introduce a special type as a wrapper for types. E.g.

[Scenario]
[Example(typeof(ExampleType<RedWidget>))]
[Example(typeof(ExampleType<BlueWidget>))]
public static void MungingWidgets<TWidget>(TWidget widget)
    where TWidget: IWidget, new()
{
    "Given a {0}"
        .f(() => widget = new TWidget());
    ...
}
