Re: [O] What does the _ in `(defun org-element-section-parser (_) ...)' stands for?

FYI, I found this today:

(To silence byte-compiler warnings about unused variables, just use a variable name that start with an underscore. The byte-compiler interprets this as an indication that this is a variable known not to be used.)

Unless you build your own from the upstream git repo, you can never be
up to date; even so, it depends on how often you build - I build from
upstream every six months or so and my current version is

GNU Emacs 25.0.50.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.14.15) of
2015-08-16

It's probably time to rebuild...
