This is useful in the context of reducing the available methods and operator overloading, when subclassing a type. Typically, when subclassing a NamedTuple type, you often don't want the <, >, <=, >=, + or * operators to work, so in that case you would want for the related methods to return NotImplemented.

Normally, when you subclass a namedtuple, it's because you want a tuple. Do you perhaps want a dataclass instead? ChrisA
