Java is the same if I remember correctly, always felt like a design failure to me.

- masklinn 1y agoIt's especially dumb for Java, because Iterator could just have been a subtype of Iterable. That's basically what Python does, the iterator protocol requires also being an iterable[0]. And Rust just blanket implements IntoIterator for every Iterator without asking. At least it's pretty easy to wrap an iterator in JS: {[Symbol.iterator]: () => it} [0] which in the rare case you implement an iterator entirely by hand will be a trivial `return self`, so much so that `collection.abc.Iterator` just provides that)
