}

function bar()
{

}

function baz()
{
    yield from bar();
}

$gen = baz();

    ["line"]=>
    int(8)
    ["function"]=>
    string(3) "foo"
    ["args"]=>
    array(0) {
    }
  }
  [1]=>
  array(4) {
    ["file"]=>
    string(18) "example.php"
    ["line"]=>
    int(12)
    ["function"]=>
    string(3) "bar"
    ["args"]=>
    array(0) {
