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