This is probably not documented, TODO for documentation

Yes, it's intentional. https://wiki.php.net/rfc/uniform_variable_syntax

Description:
------------
The code from the description now has a different output. I'm not sure if it's
intentional, so I decided to post it as a bug. It's definitely a BC change.
Also see:
http://3v4l.org/pE0UN
Test script:
---------------
<?php
$foo = [
'a' => 'b'
];
$bar = [
'b' => 'c'
];
$bar = (object)$bar;
// Note that the following line is interpreted as
// $bar->b in PHP < 7, and $bar->Array in PHP > 7.
echo $bar->$foo['a'];
Expected result:
----------------
c
Actual result:
--------------
Notice: Array to string conversion in /in/pE0UN on line 14 Notice: Undefined property:
stdClass::$Array in /in/pE0UN on line 14
