    9.4.4 Arguments Exotic Objects

    Most ECMAScript functions make an arguments object available to their code. Depending upon the
    characteristics of the function definition, its arguments object is either an ordinary object
    or an arguments exotic object.

    Arguments :
        ( )
        ( ArgumentList )
        ( ArgumentList , )

        ... AssignmentExpression
