This creates two IO collections, one for the model, one for the example set.
However, both models and both example sets, corresponding to the two iterations of the loop look exactly identical.
If I roll-up this process explicitly laying out the two iterations, such as here, this creates the expected results.
Hence, I must conclude that the Loop operator is broken? >:(
