9 ECMA Section: 15.3.5 Properties of Function Instances
10 new Function(p1, p2, ..., pn, body )
12 Description:
14 15.3.5.1 length
16 The value of the length property is usually an integer that indicates
17 the "typical" number of arguments expected by the function. However,
18 the language permits the function to be invoked with some other number
19 of arguments. The behavior of a function when invoked on a number of
20 arguments other than the number specified by its length property depends
21 on the function.
23 15.3.5.2 prototype
24 The value of the prototype property is used to initialize the internal [[
25 Prototype]] property of a newly created object before the Function object
26 is invoked as a constructor for that newly created object.
28 15.3.5.3 arguments
30 The value of the arguments property is normally null if there is no
31 outstanding invocation of the function in progress (that is, the function has been called
32 but has not yet returned). When a non-internal Function object (15.3.2.1) is invoked, its
33 arguments property is "dynamically bound" to a newly created object that contains the
34 arguments on which it was invoked (see 10.1.6 and 10.1.8). Note that the use of this
35 property is discouraged; it is provided principally for compatibility with existing old code.
