I am sorry for partial topic duplication regarding array-access.
Still, at least with `declare(strict_types=1);` auto-castings of
non-numbers should raise an error:
var_dump(false + 2);
var_dump(null + 2);
Exactly like `"" + 2`.
WDYT? Filippo

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?
Note that there is already an accepted RFC regarding rasing E_WARNING
for invalid container read array-access[1]. However, it has not been
implemented yet, due to difficulties, see the discussion on PR #2031[2].
