I beleive adding a __cast(string $type) would be a useful feature for me, very often I have a toArray method defined. I agree with you that due to unexpected edge cases with operator precedence and general type juggling that __cast should only be called on explicit (cast). I.E.: class Int { public function __cast($type) { return 'int' == $type ? 15 : 0; } } $r = new Int; var_dump($r + 1); // 2 var_dump((int) $r + 1); // 16 var_dump((bool) $r + 1); // 1
