Editorial convention for referring to intrinsics

[bakkot]

Some intrinsics have multiple names: for example, %AsyncGenerator% and %AsyncGeneratorFunction.prototype% name the same object. We should decide which we prefer, document that, and be consistent about which we use.

(This came up in #1781, e.g. 51072eb.)

The decision has already been that the dotted form should always be used, except in the Well-Known Intrinsics table, and also in the places where the non-dotted intrinsics are defined.

If there are any cases that deviate from this, let's please fix them.

Additionally, as soon as we can verify that HTML is no longer using an undotted form, it can and should be removed entirely from 262.

There's a number of uses of %Generator% and %AsyncGenerator%, at least.

it can and should be removed entirely from 262.

I think it would be worth preserving these at least in a NOTE, for documentation purposes.

[ljharb]

Generator and AsyncGenerator are top-level types, so I'd expect those to be the ones referenced.

Totally fair; I'd expect that to be an entry in Annex E.

Not sure what you mean by top-level types. Neither is directly referenceable from the global object.

The way you get at %Generator% in userland is by doing (function*(){}).prototype, and the way you get at %GeneratorFunction% is by doing (function*(){}).prototype.constructor. So %Generator% can be written %GeneratorFunction.prototype%.

[ljharb]

Sure - but if they were exposed, that's what would be.

Happy to chat on the call tho about preferring one over the other. Is there any contention about any of the globally-exposed intrinsics, and the intrinsics that are otherwise reachable dotting off of them?

Well, no, it would be the object currently called %GeneratorFunction% which would be exposed. %Generator% is more like Function.prototype.

I don't really have strong opinions, I just want it to be settled and written down somewhere.

[devsnek]

can we rename them to %(Async)GeneratorFunction.prototype% please, it is very confusing to differentiate "Generator" and "GeneratorFunction"

[ljharb]

@devsnek i'm down with that if you do the prior research and ensure HTML and 402 (and other layered specs, if any) aren't using any "old" names.

[devsnek]

@ljharb we would still leave the original names in the table

[ljharb]

The ultimate goal is to delete the old names entirely imo.
