(Core :: DOM: Core & HTML, defect)

Description

[Boris Zbarsky [:bzbarsky]]

WebIDL now has an official [SameObject] thing that we can use and specs are starting to use it.

[Boris Zbarsky [:bzbarsky]]

Actually, [SameObject] is more restricted than [Constant], so we're going to allow both for now....

Note https://www.w3.org/Bugs/Public/show_bug.cgi?id=21271 for an actual spec use.

There's no description of [SameObject] on the MDN WebIDL page.

Comment 8

[Boris Zbarsky [:bzbarsky]]

We generally only document Gecko extensions to the spec, since otherwise we'd have to throw the whole spec in there.

What documentation did you expect to see?

Comment 9

[Andrew McCreight [:mccr8]]

Ah, that makes sense.  From the name, I just assume it was some information for the benefit of the JITs.  Sorry, I should have checked the spec.

It _might_ make sense to add something pointing out that the same restrictions apply to [SameObject] as to [Constant]...  Hard to say.
