Array instances needs to have its own version of [[DefineOwnProperty]] to go along with its [[ThrowingPut]]. >> Strictly speaking step 7 needs to compose the array elements into a >> List as that is what [[Call]] takes as an argument > >If this is wrong then so is every other use of [[Call]] in the spec, >since none of them *explicitly* say that they construct a List. > Well, not quite every use of [[Call]] but a lot of them...that why I said "strictly speaking". I'd classify this as a cosmetic bug. _______________________________________________ Es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
