Elaborate on get_footer();

[yxcvbnm]

i'm a bit doubtful but i think that add_action has the default value null as third parameter, means:

Code:

add_action(.., .., .. = null)

if someone forgets the thrid parameter or believes, that null is ok, he fails. my proposal: replace the interface with

Code:

add_action(.., .., .. = array())

comments?
