    ECMA Section:       15.3.1.1 The Function Constructor Called as a Function
                        Function(p1, p2, ..., pn, body )

    Description:
    When the Function function is called with some arguments p1, p2, . . . , pn,
    body (where n might be 0, that is, there are no "p" arguments, and where body
    might also not be provided), the following steps are taken:

    1.  Create and return a new Function object exactly if the function constructor
    had been called with the same arguments (15.3.2.1).
