Hi Alan and all,

there is no necessity for these `open-paren-in-column-0-is-defun-start' , as a function def starts at the beginning of the list, if its beginning is followed by the keyword "defun".

`open-paren-in-column-0-is-defun-start'  will never be reliable WRT nested definitions.

Here is a suggestion how to solve this for Emacs Lisp:

ar-backward-defun

from

https://github.com/andreas-roehler/thingatpt-utils-core/blob/master/ar-subr.el

It should be possible to write things accordingly for other languages.
