All iterators are iterable but some iterables are not iterators.

If your code accepts only iterators then use the term *iterator*.
Otherwise the term *iterable* could be used.

It is misleading to use *iterable* if your code only accepts iterators.

If an iterable is an iterator; It is called *iterator*. The term
*iterable* implies that some instances are not iterators.
