24    ECMA Section:       15.3.5 Properties of Function Instances
25                        new Function(p1, p2, ..., pn, body )
26
27    Description:
28
29    15.3.5.1 length
30
31    The value of the length property is usually an integer that indicates
32    the "typical" number of arguments expected by the function. However,
33    the language permits the function to be invoked with some other number
34    of arguments. The behavior of a function when invoked on a number of
35    arguments other than the number specified by its length property depends
36    on the function.
37
38    15.3.5.2 prototype
39    The value of the prototype property is used to initialize the internal [[
40    Prototype]] property of a newly created object before the Function object
41    is invoked as a constructor for that newly created object.
42
43    15.3.5.3 arguments
44
45    The value of the arguments property is normally null if there is no
46    outstanding invocation of the function in progress (that is, the function has been called
47    but has not yet returned). When a non-internal Function object (15.3.2.1) is invoked, its
48    arguments property is "dynamically bound" to a newly created object that contains the
49    arguments on which it was invoked (see 10.1.6 and 10.1.8). Note that the use of this
50    property is discouraged; it is provided principally for compatibility with existing old code.
