`Set.prototype.toggle()`

1

`Set` sorely lacks a `toggle` method: ```javascript Set.prototype.toggle = function (value, toggle = this.has(value)) { return toggle ? this.delete(value) : this.size < this.add(value).size } ```

Proposal Status?

18

Was wondering what the status of this proposal was, given that it's not listed on the [TC39 Proposals page.](https://github.com/tc39/proposals). Based on an [EDiscuss thread](https://esdiscuss.org/topic/new-set-methods-again) I'm wondering if this has stalled?

Set.prototype.at

```js const aSet = new Set([1, 2, 3, 4]) console.log(aSet.at(1)) // 2 // Would be _really_ nice: console.log(aSet[1]) // 2 ```

The `value `here is not defined, should it be `element`? https://github.com/tc39/proposal-collection-methods/blob/99480f94980a69efd1f24bdd7381f571d688f53d/map-polyfill.js#L117

Extending old methods

Why do you add new methods instead of making `.add()` and `.delete()` work with several values? It will not break anything. The more names, the worse. There is no `.pushAll()`.
