/**
* File Name: function-001.js
* Description:
*
* http://scopus.mcom.com/bugsplat/show_bug.cgi?id=324455
*
* Earlier versions of JavaScript supported access to the arguments property
* of the function object. This property held the arguments to the function.
* function f() {
* return f.arguments[0]; // deprecated
* }
* var x = f(3); // x will be 3
*
* This feature is not a part of the final ECMA standard. Instead, scripts
* should simply use just "arguments":
*
* function f() {
* return arguments[0]; // okay
* }
*
* var x = f(3); // x will be 3
*
* Again, this feature was motivated by performance concerns. Access to the
* arguments property is not threadsafe, which is of particular concern in
* server environments. Also, the compiler can generate better code for
* functions because it can tell when the arguments are being accessed only by
* name and avoid setting up the arguments object.
