[FlashCodersNY] array math

[Hudson Ansley]

ah, that's a good point, obviously I missed that from the original
email. I would still prefer the less simple but easier to understand
version using total(), but I have a strong preference for
self-documenting code. Also, I was prompted to re-write your valueOf
function because it has an error in it, just in case that is what you
are using and not just an email typo... and since it might be
confusing to others following this thread (if anyone is still there
after the dive down the functional programming rabbit hole ;-)

>      for(var i:uint=0;i<this[i];i++) total+=this[i];
should be

      for(var i:uint=0;i<this.length;i++) total+=this[i];

Hudson
