Note that right now, as IE8 is pushed via Windows Update and takes over IE7's share, Firefox 3 / Gecko 1.9 moves to the front of the market share by "user-agent rendering engine" race.

Of course, IE8 does not implement string indexing, so Array.prototype.pop.call("abc") returns undefined in IE8. But it does not throw.

Same for IE7 -- undefined result, no throw.
