Review comment:
I would suggest using a static object that is weighted that is internal.
Using `null` hides useful information when debugging the caches contents.
Please also update the method comment saying that the state cache should be
namespaced for this object to prevent collisions (like BagUserState).
Like
```
private static class IterableCacheKey implements Weighted {
static INSTANCE = new IterableCacheKey();
getWeight() {
return 0;
}
}
```
