No real need for any -region functions IMO, check this out.

(This, in turn should be integrated in `interactive' and/or
`defun', see the other thread ... `cl-defun' with it's default
values is interesting, in principle we could even decouple
argument docstrings and have all that fully automated except
for the reading and writing parts ...)

(defun use-region ()
  (when (use-region-p)
    (list (region-beginning) (region-end)) ))

(defun test-dwim (&optional beg end)
  (interactive (use-region))
  (or beg (setq beg (point-min)))
  (or end (setq end (point-max)))
  (message "%d %d" beg end) )
