For the (rare) case of infinite iterators of iterators, use `flatMap` with the identity function.
For the (rare) case of infinite iterators of iterators, use [`Iterator.prototype.flatMap`](https://tc39.es/ecma262/multipage/control-abstraction-objects.html#sec-iterator.prototype.flatmap) with the identity function.

```js
function* p() {
function* selfCountingSequenceHelper() {
for (let n = 1;; ++n) {
yield Array(n).fill(n);
}
}
let repeatedNats = p().flatMap(x => x);
let selfCountingSequence = selfCountingSequenceHelper().flatMap(x => x)
