Bug description:Order of traits in use statement can cause a fatal error

Description:
------------
The fatal trigger only occurs when the order of the use statement is

class HTMLHelper implements Helper
{
  use TextUTF8, TextArea, HTMLAttributes;
}

If the use statement is reordered... 

class HTMLHelper implements Helper
{
  use TextArea, HTMLAttributes, TextUTF8;
}

then code is fine. 

I guess that some testing of abstract methods is missing somewhere?



Test script:
---------------
https://gist.github.com/1595674

Expected result:
----------------
No fatal error

Actual result:
--------------
PHP Fatal error:  Can't inherit abstract function
HTML\HTMLAttributes::text() 
(previously declared abstract in HTML\TextArea) in 
/var/www/framework.localhost/htdocs/bug.php on line 55
