It's more efficient to create an array here instead of using the
arguments object. The array solution was about 20%-30% faster,
tested with swf8, swf9, dhtml (FF3, Saf3, Opera9). You can verify
with this simple testcase:
Interesting! I guess these script engines are just not optimized for
these cases. I'm still living in the Lisp world where `arguments`
would be a stack-allocated list, and only copied to the heap if you
captured it in an upward funarg...
I've made your suggested change. Thanks.
