Joshua,

I totally agree with you. However, there are at least two workarounds for this:
(1) Use a wrapper function. Find out how on my blog:

(2) Even more pragmatic is the following method suggested by Theo from Iconara: Use ActionScript’s …rest argument

function( item : *, â€¦ignored ) : * {
// do the magic
}

Regards,
Daniel

Haha, well they don’t have to be that ugly, alot of it is determined by the way you code it. Nevertheless, read this, you might like the topic/tone:

I agree completely.

However, you don’t need to name the second and third arguments explicitly, you can use …rest instead:

function( o:*, …rest ) : void { }

It’s a bit shorter, but still not as terse as Ruby.
