+   File Name:          15.3.5-1.js
+   ECMA Section:       15.3.5 Properties of Function Instances
+   new Function(p1, p2, ..., pn, body )
+
+   Description:
+
+   15.3.5.1 length
+
+   The value of the length property is usually an integer that indicates
+   the "typical" number of arguments expected by the function. However,
+   the language permits the function to be invoked with some other number
+   of arguments. The behavior of a function when invoked on a number of
+   arguments other than the number specified by its length property depends
+   on the function.
+
+   15.3.5.2 prototype
+   The value of the prototype property is used to initialize the internal [[
+   Prototype]] property of a newly created object before the Function object
+   is invoked as a constructor for that newly created object.
+
+   15.3.5.3 arguments
+
+   The value of the arguments property is normally null if there is no
+   outstanding invocation of the function in progress (that is, the function has been called
+   but has not yet returned). When a non-internal Function object (15.3.2.1) is invoked, its
+   arguments property is "dynamically bound" to a newly created object that contains the
+   arguments on which it was invoked (see 10.1.6 and 10.1.8). Note that the use of this
+   property is discouraged; it is provided principally for compatibility with existing old code.
