Still it is a key property of the language which we can't simply change. Also mind this: All input data are strings and some databases also return data as string. So code like if ($_GET['id'] > 0) or if ($db->fetchRow()[0] == 12) which is common will break. Maybe using different sets of operators would have been better, but that should have happened 20 years ago not now. Also mind consistency: If you change this you probably also have to change other places where implicit conversion happens, i.e. array keys. In the end you get a complete new incompatible language and can throw away most libraries and so on. So in case you have a Tardis, DeLorean with Flux Capacitor or any other time machine I'm happy to support you in the past, but not this late. johannes
