23    File Name:          10.1.6
24    ECMA Section:       Activation Object
25    Description:
26
27    If the function object being invoked has an arguments property, let x be
28    the value of that property; the activation object is also given an internal
29    property [[OldArguments]] whose initial value is x; otherwise, an arguments
30    property is created for the function object but the activation object is
31    not given an [[OldArguments]] property. Next, arguments object described
32    below (the same one stored in the arguments property of the activation
33    object) is used as the new value of the arguments property of the function
34    object. This new value is installed even if the arguments property already
35    exists and has the ReadOnly attribute (as it will for native Function
36    objects). (These actions are taken to provide compatibility with a form of
37    program syntax that is now discouraged: to access the arguments object for
38    function f within the body of f by using the expression f.arguments.
39    The recommended way to access the arguments object for function f within
40    the body of f is simply to refer to the variable arguments.)
