    (compare x y)
    
    Polymorphic compare. Returns -1, 0, 1 for x < y, x = y, x > y
    respectively. Differs from the primitive comparators in that it first
    checks to see whether either x or y implement a 'compare' method which
    can compare x and y. If so it uses that compare method. If not, it
    delegates to the primitive comparators.
