In Java and other C-derived languages, an array literal can have a comma after
the last element, for example:
int[] numList = {1, 2, 3,};
In ActionScript, you can do the same thing:
var numList:Array = [1, 2, 3,];
In both cases, the array has a length of 3. The trailing comma is basically

Yes, I think it matters quite a bit. It would be very easy for someone, even in
their right mind, to unintentionally have an extra comma somewhere in the
middle of a long array literal and not notice it. And the compiler would not

As you said, nobody in their right mind would do it. One of the hallmarks of
a well-designed language, IMO, is that it doesn't silently allow you to do
things that no one in their right mind would do. At least a compiler warning
