It’d be great if all iterables were indeed the same in this regard.
I didn't reply to this last sentence. I don't agree that all iterables
(we don't control the universe of such things, so perhaps you mean all
standardized or built-in iterables) vend iterators with return methods.
It's rare to both break from a for-of loop and want to iterate more
after, so you're in hard-cases-make-bad-law land right there.
Iterators are best used by getting fresh ones and consuming them till
"done" (whether exhausted or not). `return` is required only if an
iterator hangs onto a scarce-enough resource. Many (most?) iterators do not.
