Consider pointing to in-progress proposals that document web reality

[domenic]

So far I know of:

• https://github.com/sebmarkbage/ecmascript-string-left-right-trim
• https://github.com/tc39/Function-prototype-toString-revision
• https://github.com/claudepache/es-regexp-legacy-static-properties
• Some in-progress proposal from @erights and @ljharb on Error.prototype.stack; is that online somewhere?

There are also a number of important open bugs, which I've tagged as "web reality" on the TC39 repo.

[ljharb]

No, it'll be System.getStack, and I hope to have something written up before September.

There's also https://github.com/claudepache/es-regexp-legacy-static-properties as well.

[domenic]

I mean, we also need to have an Error.prototype.stack getter for web compatibility (annex B it if that makes you feel better). @erights seems to agree on that point last we talked.

[ljharb]

Oh, right, that's true. I'll make sure that's included in the writeup.

tc39/ecma262#664

Can someone please tag those issues with the “web reality” label?

Closing this issue in favor of #29.
