The "?:" meaning is that the grouping will not be accessible by
`match-string' and friends and that's intended. It doesn't change
regexp's behavior for matching a beginning of defun, but you can't get
the type easily.
If getting the type is the issue for you, one way to do it is:
(when (looking-at python-nav-beginning-of-defun)
(let* ((match (split-string (match-string-no-properties 0)))
(type (car match)))
(name (cadr match))
(list type name)))
Regards,
Fabián.
