Comment (by tazotodua):

 will this ever be solved?
 for example,we have:

 {{{#!php
 add_action('wp_head','my_function');

 function my_function($first=false){
     var_dump($first); exit;
 }

 }}}

 it doesnt show false, instead something empty string is passed from the
 action... why? I think actions should not touch the arguments of
 functions..
