Worth reading up on the `arguments` variable in the spec[1] (warning,
multi-meg PDF). Also check out Function#apply, which is probably what
you're looking for:
var Thingy = Class.create((function(){
function foo() {
bar.apply(this, arguments);
}
function bar(a, b, c) {
alert("a = " + a);
alert("b = " + b);
alert("c = " + c);
}
return {foo: foo, bar: bar};
})());
var t = new Thingy();
t.foo(1, 2, 3);
// Alerts "a = 1", then "b = 2", then "c = 3"
The first argument to Function#apply is the context (the value `this`
should have within the call). The second argument is an array (or
array-like thing, such as `arguments`) of arguments to pass to the
function.

No, it's local to the function scope, like the formal arguments and
vars inside the function (in fact, like them it's a property of the
variable object for that execution context).
