Exercise 1.35.  Show that the golden ratio ϕ (section 1.2.2) is a fixed point 
of the transformation x ↦ 1 + 1/x, and use this fact to compute ϕ by means of 
the fixed-point procedure.

------------------------------------------------------------------------

This follows directly from the definition of ϕ.

(fixed-point (lambda (x) (+ 1 (/ 1 x))) 1.0)
