For example I would be very surprised if there was a plan to expose [[Scope]], [[Code]], etc. > I agree. To be clear, that was not what I was asking for. What I was suggesting was that a WebIDL user agent might support something like: > > //returns true or false > Object.isPlatformObject(obj) OK, I understand now. Being a platform object is something that is relative to a given implementation of a set of IDL fragments, so I don't think it's something that can be put on Object. I am not sure that this would be useful enough to warrant adding, however.
