To me the main challenges seem to be to find a syntax that feels natural, and then the technical feasibility of actually implementing and maintaining this in the engine. It probably does feel awkward to have declarations on top of every file. And it would mean you need to make a conscious choice for every new file and every new library. Not just a "yes or now", but to pick a specific version or edition number. You would periodically modify your code to increase this number. So doing this on "package level", whatever this means, would have clear advantages. To some extent this awkwardness could be seen as the price for having a language that historically started somewhere very different from where we would like to see it in the future. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
