using flyspell-region from another function

Because I want to use a single function for spelling, rather than having to 
call ispell, aspell,

flyspell directly.

But that already exists...?

It can look like this:

(defun sort-second-field (beg end)
(interactive "r")
(sort-fields 2 beg end) )
(defalias 's2f #'sort-second-field)

You can also make it more generic, for example this which is
DWIM interactively (region if region, 0->point if not), and
from Lisp with args beg->end, and from Lisp w/o args the whole
buffer! so 4 ways to invoke!

(defun count-chars (&optional beg end)
(interactive
(if (use-region-p)
(list (region-beginning) (region-end))
(list (point-min) (point)) ))
(message "%d" (- (or end (point-max))
(or beg (point-min)) )))
