You say that as fact but you must know it is a matter of opinion: I would say you should match the language idioms. For example, Python iterators and generators work by raising/throwing when there are no more items: it is fully expected and will always happen when you write a for-in loop.

That seems like bad design. Rust iterators return an Option<T>, for example.

  In Python a lot of flow control uses exceptions as it's cheaper to ask for forgiveness rather than permission and then still have to deal with errors.
