/**
   File Name:          10.1.6
   ECMA Section:       Activation Object
   Description:

   If the function object being invoked has an arguments property, let x be
   the value of that property; the activation object is also given an internal
   property [[OldArguments]] whose initial value is x; otherwise, an arguments
   property is created for the function object but the activation object is
   not given an [[OldArguments]] property. Next, arguments object described
   below (the same one stored in the arguments property of the activation
   object) is used as the new value of the arguments property of the function
   object. This new value is installed even if the arguments property already
   exists and has the ReadOnly attribute (as it will for native Function
   objects). (These actions are taken to provide compatibility with a form of
   program syntax that is now discouraged: to access the arguments object for
   function f within the body of f by using the expression f.arguments.
   The recommended way to access the arguments object for function f within
   the body of f is simply to refer to the variable arguments.)
