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.
