Output operation is missing a context parameter

[cjundt]

There is no way to get context information when setting output data on a step setup.
This is especially required in the context of a loop like ForEach step.
For instance :

builder
    .StartWith<SayHello>()
    .ForEach(data => new List<int> { 0, 1, 2, 3, 4 })
        .Do(x => x
            .StartWith<DisplayContext>()
            .Output( (step, data, context) => data.Items[context.Item] = step.Return )
            .Then<DoSomething>())
    .Then<SayGoodbye>();
