I think allowing globals/lexicals to be passed by value doesn't make 
much sense, you could just use a regular parameter for that. And that 
would bring another inconsistency to PHP, and would mean that PHP is 
discouraging the use of $_GLOBALS, that was created to discourage to use 
of 'global $var'.
