michael@0:    Description:
michael@0: 
michael@0:    15.3.5.1 length
michael@0: 
michael@0:    The value of the length property is usually an integer that indicates
michael@0:    the "typical" number of arguments expected by the function. However,
michael@0:    the language permits the function to be invoked with some other number
michael@0:    of arguments. The behavior of a function when invoked on a number of
michael@0:    arguments other than the number specified by its length property depends
michael@0:    on the function.
michael@0: 
michael@0:    15.3.5.2 prototype
michael@0:    The value of the prototype property is used to initialize the internal [[
michael@0:    Prototype]] property of a newly created object before the Function object
michael@0:    is invoked as a constructor for that newly created object.
michael@0: 
michael@0:    15.3.5.3 arguments
michael@0: 
michael@0:    The value of the arguments property is normally null if there is no
michael@0:    outstanding invocation of the function in progress (that is, the function has been called
michael@0:    but has not yet returned). When a non-internal Function object (15.3.2.1) is invoked, its
michael@0:    arguments property is "dynamically bound" to a newly created object that contains the
michael@0:    arguments on which it was invoked (see 10.1.6 and 10.1.8). Note that the use of this
michael@0:    property is discouraged; it is provided principally for compatibility with existing old code.
