--FILE--
<?php

    public $dummy { set {} }

    public function init() {
        $this->prop = 1;
    }
}

$c = new C;

// Okay, as foreach skips over uninitialized properties.
foreach ($c as &$prop) {}

$c->init();

try {
    foreach ($c as &$prop) {}
} catch (Error $e) {
    echo $e->getMessage(), "\n";
