My mistake, I did mistype the code I was using to reproduce this in immediate mode, and using the
correct method name does indeed fix it.
However, in my actual code that is using the magic methods, it's not working on 7.3, but is
working on 7.2 and 7.1. You can see a failing build here: https://travis-ci.org/BapCat/Propifier/builds/474430892
Code is here: https://github.com/BapCat/Propifier/blob/master/src/PropifierTrait.php#L206
Failing test is here: https://github.com/BapCat/Propifier/blob/master/tests/PropifierTraitTest.php#L25
The trait takes protected methods (like getXyz() and/or setXyz()) and turns them into strongly-typed
properties (like $obj->xyz).
I don't believe it's a bug in the code, since it runs normally on 7.1/7.2 (and was running
fine on earlier versions before adding type hints, etc.)

Hi,
I'm quite confused by your example, in particular:
i) Your code doesn't include __get, which is what I think you were reporting.
ii) The code in your example works the same on 7.3 as previous versions of PHP - https://3v4l.org/97X3q
iii) What I think you're reporting, does work on 7.3: https://3v4l.org/5p6u3
Please can you clarify what you're reporting.

Your example doesn't show __get, it shows __test, which can be correctly used like this https://3v4l.org/M8BtH

Description:
------------
If you have a __get or __set method defined in a trait, they can no longer access private/protected
variables defined in the class that implements them. This worked < 7.3.
I wasn't able to find any information on this breaking change in the PHP 7.3 changelog.
Test script:
---------------
trait T {
public function __test($name) {
return $this->$name;
}
}
class Test {
use T;
private $test = 'asdf';
}
$test = new Test();
echo $test->test;
Expected result:
----------------
'asdf' is echoed.
Actual result:
--------------
PHP Warning: Uncaught Error: Cannot access private property Test::$test in php shell code:1
