one reason why circular references are not easy to detect here. (The sheet of the returned

Another reason there's little value in attempting to detect circular references here is
that only direct circular references could be detected. If the cycle involved two or more

Logic to detect evaluation cycles of all kinds has been coded in EvaluationCycleDetector
