Indeed. To clarify: the case-distinction is made in ES5 as well, although it is implicit there because of the use of [[GetOwnProperty]] versus [[GetProperty]] (see ES5 8.12.5 [[Put]]). The test is needed to distinguish updating of "own" data properties (8.12.5 step 3.b) from adding a new own data property (8.12.5 step 6.b). As [[GetProperty]] is removed from ES6, we need to test the Receiver to figure out what case we're in. Cheers, Tom
