On the flip side, coalesce() etc would introduce another keyword, which would be a BC break, unless we also manage to get keywords-as-identifiers working and accepted for the same release. I wouldn't mind betting there are quite a few applications out there with a function/method called coalesce() defined... I know there's at least one, because I work on it regularly, and github has over 100,000 hits for it (the vast majority of these are in SQL strings but I still found 4 PHP functions/methods on the first 3 pages): https://github.com/search?q=coalesce+language%3Aphp&type=Code -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
