> Right now, the runner intercepts calls to apply() and replaces transforms as we go. This means that there is no "original" user graph. For portability and misc architectural benefits, we would like to build the original graph first, and have the runner override later.
> Some runners already work in this manner, but we could integrate it more smoothly, with more validation, via some handy APIs on e.g. the Pipeline object.
