Hi,  
to be honest I don't see much of a difference between

```javascript
for (const item of multi[^alt]) …
const arr = [...multi[^other]];

```

and

```javascript
for (const item of multi.alt()) …
const arr = [...multi.other()];

```

So where exactly is the benefit?

I'd say a quick switch of default iterator implementation. Adding an alias for a generator function. Skipping misleading function call as well.

Related question, is it possible to alias a function?

```javascript
class Foo
{
  *bar() {}
  *baralias() (this.bar)
  // Normally used like
  *barnormal() { return this.bar.bind(this); }
}

```

The function call is not misleading at all, why do you think it is confusing?

Sure, you can just write

```javascript
class Foo {
   *bar() { … }
   get alias() { return this.bar }
}

```

or

```javascript
Foo.prototype.anotherAlias = Foo.prototype.bar;

```
