An exception to this would be if the list represents an atomic set of items that are never queried independently;
in these cases, however, it is probably best to wrap it in a struct.
For example, to represent the set of containers in a pod, we may make a `type PodContainers struct { Name string, Containers []string }` and have a

	fakeIPSetDeps.AssertExpectations(t)
