Subject: Array key access on non-array values - to be made illegal?

Hello,

I just stumbled upon behavior that seems to "fail silently" regardless of
its very questionable validity:

<?php

$a = 1;

var_dump($a[123]); // NULL, no notice

https://3v4l.org/b3rDr

Are there specific reasons why no notice is thrown? Is it by design? If so,
does anyone remember why?

I haven't checked if this affects other types too. I know that an
assignment to an array key of a non-array would cause a cast of the value
to `array`, but a mere read operation should surely cause a notice to be
raised in the above scenario.

Cheers,
