/**
* This version is only supported for a Cluster running the same code as the test environment, and permits
* ergonomic cross-node behaviours, without editing the cross-version API.
*
* A lambda can be written tto be invoked on any or all of the nodes.
*
* The reason this cannot (easily) be made cross-version is that the lambda is tied to the declaring class, which will
* not be the same in the alternate version. Even were it not, there would likely be a runtime linkage error given
* any code divergence.
