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.)

There is up to date ... And up to date😉 funnily enough I run a near
bleeding edge version of Emacs from home brew and org 8.2.10 from Melpa.

Sounds
I guess it is a required signature for the function (i.e. some other
function will call it with some argument), and _ indicates it is not
used in the body. If you were to give it the arg a name, then checkdoc
would complain about it not being in the docstring.

just out of curiosity, a few functions in org-element.el contain _ in
their parameter list, but its not used in the body.
What does it stand for?
