Can the result be converted to a list? As that is what it returned before.

    return list(super(RESTObject, self).__dir__() | self.attributes.keys())

The__dir__ method can return any sequence and will be converted into a list and sorted automatically. For example, if you return a set or any other sequence,dir(obj) will always be a list.

classMyObj:def__dir__(self):return {'abc','xyz','def',}obj=MyObj()dir(obj)['abc','def','xyz']

If you like we can convert it in the method directly, if for nothing else, to be more explicit, though the result is the same in either case.

I (for selfish reasons) would like it to return a list. As I am going to be working on adding type-hints to that code in the future 😊 But not necessary.

And not necessary, because I think I will be adding a type-hint for the return value ofIterable[something], most likely.

Sounds good to me. Feel free to apply the above suggestion (or not)

Looking forward to type hinting!

Worth mentioning that it'susually not necessary to provide type annotations or type hints for certain magic methods, since their return type is implied because there's no way to implement them to return a different type.

For example, the return type for methods like__str__,__repr__,__len__,__dir__, are known to IDEs and type checkers like MyPy automatically because the returned type must be valid, otherwise aTypeError is raised.
