Hi Brian: why did you reopened this ticket?
Thanks!

Here are some clarifications:

This will not throw exception in IE < 8.

If you have such array:

var testArray = [ 1, 2, 3, ];

and check array's length, like this:

alert(testArray.length);

the reported length will be different. IE will report 4, the other browsers 3. The right behaviour is not clearly specified in ECMA-262-3, but in ECMA-262-5 it is pretty clear:
"If an element is elided at the end of an array, that element does not contribute to the length of the Array."

You probably meant object literals. IE < 8 will throw syntax error if you put comma after the last element, like this:

var myObject = {

a: 1,

b: 2,

c: 3,

};

In ECMA-262-3 this is not allowed, but in ECMA-262-5 it is.

However, I am going to accept your patch in order to avoid such misunderstandings.
