Comment:

 [[attachment:20163.patch]] Should be a very good start on removing call
 time pass by reference.  I've given the admin and front end a light
 testing (hitting most pages and functions) and ensured that there are no
 php syntax errors in any php files.  This was a mostly scan, verified with
 some automated grepping.

 If you look on your own, be careful of `array(&$var);` as that's perfectly
 valid.  Changing a piece of code like this will break things.

 {{{
 do_action_ref_array( 'wp_default_styles', array(&$this) );
 }}}
