Subject: Raise E_NOTICE for null castings
From: zoeslam@gmail.com (Filippo Tessarotto)

Hi, I would like to propose an RFC to raise an E_NOTICE when a variable 
"initialized" to null is casted to other types:

$foo = null;
var_dump($foo['bar']);
var_dump($foo . 'bar');
var_dump($foo + 2);
var_dump($foo & 2);
// At the time being, this code produces no errors

The eventual vote may be split one for each case.

What do you think?

Best regards, Filippo
