I noticed that most Array methods perform [[HasProperty]] checks on

Array#indexOf and Array#lastIndexOf do not. Firefox 3, Safari 4,
Chrome 2 all seem to check [[HasProperty]] for Array#indexOf and
lastIndexOf.
Is this an oversight on the draft or did the browser vendors miss
something ?
Browser implementations, starting with Firerfox 1.5 / SpiderMonkey
(JS1.6), preceded the spec, so the oversight is probably on TC39's
part. I don't recall this coming up and a rationale for diverging from
the de-facto standard being given.
