The following is `reduce' from which the cl keywords feature is
removed; same as `(apply FUNCTION (append SEQ nil))':
(defun shr-reduce (function seq)
"Reduce two-argument FUNCTION across SEQ."
(or (listp seq) (setq seq (append seq nil)))
(let ((accum (pop seq)))
(while seq
(setq accum (funcall function accum (pop seq))))
accum))
