class Cycle
    def cycle(*args)
      args[((@_cycles ||= Hash.new(-1))[args.hash] += 1) % args.size]
    end
end

More beautiful code plees?

And a version with less repetition:



(let ((ht (make-hash-table :test #'equal)))

  (defun cycle (&rest args)

    (symbol-macrolet ((h (gethash args ht)))

      (unless h    (setf h args))

      (pop h))))
