michael@0:    ECMA Section:       Activation Object
michael@0:    Description:
michael@0: 
michael@0:    If the function object being invoked has an arguments property, let x be
michael@0:    the value of that property; the activation object is also given an internal
michael@0:    property [[OldArguments]] whose initial value is x; otherwise, an arguments
michael@0:    property is created for the function object but the activation object is
michael@0:    not given an [[OldArguments]] property. Next, arguments object described
michael@0:    below (the same one stored in the arguments property of the activation
michael@0:    object) is used as the new value of the arguments property of the function
michael@0:    object. This new value is installed even if the arguments property already
michael@0:    exists and has the ReadOnly attribute (as it will for native Function
michael@0:    objects). (These actions are taken to provide compatibility with a form of
michael@0:    program syntax that is now discouraged: to access the arguments object for
michael@0:    function f within the body of f by using the expression f.arguments.
michael@0:    The recommended way to access the arguments object for function f within
michael@0:    the body of f is simply to refer to the variable arguments.)
