+    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.)
