The helper struct ReconcileStackSession makes engineering more difficult because it duplicates local variables, making it unclear which are in play, and obscuring side-effects. It doesn't do anything that couldn't better be done by funcs (or methods on *ReconcileStack), since it doesn't include any state that needs encapsulation.
