We do not consider new warnings, including deprecation notices, as breaking changes. We know that due to error handlers it can have an effect, but it's just part of the process. I disagree with Stas on the value. The precedence is wrong, and I know of a few codebases which had bugs due to this. In every case, the fix was to avoid it altogether. I agree with statement from the RFC: > As left-associative ternaries are almost certainly bugs, the impact of this > change should be minimal. Thanks, Nikita, on putting this together. It's definitely not a "fun" RFC. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
