Initializing array element with reference returned by function not possible

[ohyeaah]

Description

Please note that when removing the ampersand at line 13 it seems to work but then it's no longer a reference.

<?php
function &moh()
{
  static $o;
  return $o;
}

// works
$jo = [0];
$jo[0] = &moh();

// shows error
$jo = [&moh()];

Resulted in this output:

Fatal error: Can't use function return value in write context in /home/user1/Schreibtisch/test.php on line 13

But I expected this output instead:

PHP Version

PHP 8.4.4

Operating System

3v4l

Fair. This is similar to foo() = 'bar';, which could also work if foo() returns a reference. The compiler is too strict in this case.
