beg still needs a check like

otherwise it could match inside a string or comment
I have the feeling that this should return the local list
at point, even if inside a string or comment.
Yes, but that would be reported by pps. However, when point is at
opening delimiter, this is not recognised by pps. Then we must be sure
not being inside a string or comment, where an opening delimiter is
meaningless, i.e. just a literal.

IMO all needed is  something like

(beg (or (nth 1 (parse-partial-sexp...))

          (and (eq 4 (car (syntax-after (point))))
               (not (nth 8 (parse-partial-sexp...))
               (point)))))
Should both fail, there is not list at point.
Thank you.  I think i got what you mean.
I need to invert the order of the above `or':
(nth 1 (parse-partial-sexp...))
need to appear the second.  Otherwise,
(with-temp-buffer
   (insert "(foo (a b) bar)")
   (goto-char 6)
   (list-at-point))

will return:
(foo (a b) bar)
instead of:
(a b)

Ah, good catch. Thanks back.
