Can we add a comment describing the goal of the test.

My understanding is that we want to make sure the map is correctly constructed to only have decrements.

Does this also (want to) check that no diagnostic is raised?

Should we also check the map `CounterDirection` "map" has a size as expected (should there just be 1 or 3 elements)? Edit: ah maybe the `Bindings.size()` does that

This would apply to the other testcases here
