Array.lastIndex polyfill contains no set accessor

[overly-engineered]

The proposal for Array.prototype.lastIndex as defined here contains both get and set accessors.

The polyfill implemented here contains only the get accessor https://github.com/zloirock/core-js/blob/master/packages/core-js/modules/esnext.array.last-index.js.

Can I either update this polyfill to include a setter as well or as the proposal is now paused can I remove the current lastIndex polyfill as it is unlikely to be moved on further.

As you can see in the spec draft, .lastIndex should be only a getter, so the core-js implementation is correct.

I'm not sure will this proposal be available in core-js@4 or not because of the current state of the proposal, will see it later.

Oh, that's my bad, I was looking at lastItem. It would be great to see it removed if the proposal starts to languish. Cheers
