F# fields are immutable unless you specify they are mutable. The question I posed cannot be solved with exclusively immutable fields. This is basic computer science, and ChatGPT has the knowledge but fails to infer this while providing flawed code that appears to work. An inexperienced developer would eventually shoot themselves in the foot, possibly long after integrating the code thinking it was correct and missing the flaws. FYI, your Python code works because of the mutation "extend()": alice.children.extend([bob, carol])
