Your Python example is far from idiomatic, though. If a Python programmer were forced to write `Stuff`, they'd write something like: class Stuff: def __init__(self): self.a_list = [1,2,3,4] def __iter__(self): return iter(self.a_list) --- or do what the other person did, and make `__iter__` a generator, which isn't necessary in this case but is much more flexible.
