Thanks for the suggestion! This does work for SpiderMonkey, at least in some case, but it might not work as nicely for other JS engines (including SpiderMonkey in the future! :) Jan's suggested approach, which I've implemented in bug 1040593, seems nicer and allows the |array[length - 1] = <default>| line to be skipped.
