They are, but for protocols we usually use dunder names. "_fields" is a common enough attribute name for all kinds of objects, not necessarily namedtuples. Can we at least check if the class is a tuple subclass and then use its '_fields' for sorting? > I can add a check to at least check the value of _fields is an iterable of > strings.
