[Webkit-unassigned] [Bug 140420] JavaScript identifier incorrectly parsed if the prefix before an escape sequence is a keyword

--- Comment #3 from Alan Tam <Tam at SiuLung.com> ---
It is not limited to for..in, but all keywords. Indeed, object literal is another way to trigger the bug.

> ({while\u00e9dit:1})
SyntaxError: Unexpected identifier '\u00e9dit'. Expected a ':' following the property name 'while'.

Again, this works in Chrome and Firefox, returning this hash: {"whileédit":1}
