[Python-ideas] Idea: PEP 3132 – Extended Iterable Unpacking for custom classes

Basically, I think it would be need if we could write first, *tail = np.array([1,2,3]) and have tail be a np.ndarray. Currently, the result is list. Either, python could try initializing the object using the received type, or one could introduce a new dunder classmethod __from_iterable__ that custom classes can implement.
