  24     ECMA Section:       15.3.1.1 The Function Constructor Called as a Function
  25
  26     Description:
  27     When the Function function is called with some arguments p1, p2, . . . , pn, body
  28     (where n might be 0, that is, there are no "p" arguments, and where body might
  29     also not be provided), the following steps are taken:
  30
  31     1.  Create and return a new Function object exactly if the function constructor had
  32         been called with the same arguments (15.3.2.1).
