    ECMA Section:       15.3.4  Properties of the Function Prototype Object

    Description:        The Function prototype object is itself a Function
                        object ( its [[Class]] is "Function") that, when
                        invoked, accepts any arguments and returns undefined.

                        The value of the internal [[Prototype]] property
                        object is the Object prototype object.

                        It is a function with an "empty body"; if it is
                        invoked, it merely returns undefined.

                        The Function prototype object does not have a valueOf
                        property of its own; however it inherits the valueOf
                        property from the Object prototype Object.
