If removing it would make scalar types work differently from non-scalar types, it's not a good idea. Also, I don't see a reason why not have both declarations mean nullable type - the intent is clear in both cases, it's not like it can be confused with something else. -- Stas Malyshev smalys...@gmail.com -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
