 hello.
 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..
