favorite subject DWIM

[Emanuel Berg]

I've done this so many times each time doing it in a slightly
different way (I'm sure) so I thought one would do an "ideal"
DWIM function and find out once for all how to do it...

So instead of "(list bg ed)", do something funkadelic...

?

(defun test-dwim (&optional beg end)
  (interactive (when (use-region-p)
                 (list (region-beginning) (region-end)) ))
  (let ((bg (or beg (point-min)))
        (ed (or end (point-max))) )
    (list bg ed) ))

    (set-mark 10)
    (forward-line 3)
    (call-interactively #'test-dwim) ) ; (10 500)

  (call-interactively #'test-dwim)     ; ( 1 604)

  (test-dwim 30 100)                   ; (30 100)

  (test-dwim)                          ; ( 1 604)
)
