Sometimes I got a infinity iterable sequences, I may want a partial spreed
syntax. `...iterableObject{from, to}`
For example:
```js
function *fibonacci() {
let a = 0, b = 1
while(1) {
[a, b] = [b, a + b]
yield a
}
}
console.log([...fibonacci(){3, 5}]) // [3, 5, 8]
```
For a finite list, it is similar to [...list].slice(from, to)
```js
const arr1 = [1, 2, 3, 4],
arr2 = [5, 6, 7, 8]
console.log([...arr1{2}, ...arr2{1}]) // 3, 4, 6, 7, 8
