Description

The following code:

<?php
set_exception_handler(function ($e): void {
    var_dump(set_exception_handler('is_int'));
});
throw new \Exception;

Resulted in this output:

NULL

But I expected this output instead:

object(Closure)#1 (1) {
  ["parameter"]=>
  array(1) {
    ["$e"]=>
    string(10) "<required>"
  }
}

PHP Version
