Description:
------------
The E_STRICT option purports to issue warnings when 
using deprecated features. I would like to see warnings 
issued when using the array notation of accessing 
characters in a string, since this has been deprecated 
since PHP 4 and can cause problems ( as seen in
http://bugs.php.net/bug.php?id=29271 )

Reproduce code:
---------------
$test = 'blah';

$test[2] = 'x'; // <-- would like this to issue
                //     an error of type 2048

Expected result:
----------------
$test == 'blxh' and an error that the array notation is 
deprecated, use {} notation instead

Actual result:
--------------
$test == 'blxh' and no error of any kind
