> SideInputs are not supported equally by all runners. Implementing assertions as a main input and a serialized assertion allows runner implementors to test their implementations prior to constructing side inputs.
> satisfies is the same, but accumulates the entire input into a single pane which it takes as a main input.
> containsInAnyOrder encodes the expected elements as they need not be serializable, and then can be implemented in terms of satisfies.
> empty can be implemented by failing if provided with any elements, so long as the success counter is not the means by which success is measured.
