RFC proposes to emit warning, but the provided code throws unrelated "Unsupported operand types" exception.
I see, that after few weeks of work, the implementation (just few lines of C code) is still hackish and incomplete. This makes me think that, the feature can't be cleanly implemented, and I vote against it. Thanks. Dmitry. ________________________________ From: Niklas Keller <m...@kelunik.com> Sent: Wednesday, August 31, 2016 10:58:16 AM To: Dmitry Stogov; Christoph M.

Aug. 2016, 08:37: I vote NO, because the implementation introduces more problems than intents to fix. For example the following code starts to throw exception: <?php $a = [null]; $c = null; var_dump($a[0][0] + $c[0]); ?> Array access on null should always throw IMO. BTW, I'm not against the feature, I'm against the implementation. It's just can't be committed in current state. I think we vote on features, not implementations. Therefore you should probably have voted yes. Thanks. Dmitry. ________________________________ From: Christoph M.
