Actionscript: Calling function with unknown arguments count

Question

For example i have function declared in AS3.0 class:

private function log():void{
// working with arguments directly here
}

I'm calling:

log('some stuff',object,array,etc);

Then i'm calling:

log('ok');

Ofc FlashBuilder throws exception with: type 1137: Incorrect number of arguments. Expected no more than 0

How to do it?

Update

In javascript it's possible. But in AS not, isn't it's ECMA based? Why so strict...

Update

Ok nvm. Created like that atm: log(m1:*=null,m2:*=null,m3:*=null,m4:*=null,m5:*=null):void{}

solution as well, but kinda ugly :), each time to call log(['something']) — Somebody

You can use the ... rest parameter for that:

http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/statements.html#..._(rest)_parameter

Example from the docs:

function average(... args) : Number{
    var sum:Number = 0;
    for (var i:uint = 0; i < args.length; i++) {
        sum += args[i];
    }
    return (sum / args.length);
}
