The Renaissance VM has been open sourced. The official contribution of IBM Research to the open source community can be found here: The Renaissance Virtual Machine: Open Source Release Announcement.

The code is already posted to GitHub and somewhat extended to make it actually useful. Please feel free to head over to http://github.com/smarr/RoarVM, play with the code, try the VM with your image, and report back.

The official announcement will be send out in the next couple of days, but any feedback we could get before hand would allow to fix issues before the community gets started with the VM.

Now it seems to be a good time to philosophize about the future language development of PHP again. To promote this discussion, I backported my Traits-patch to PHP 5.3, fixed some bugs, and used GitHub to publish it. Lets hope that this will allow a painless maintenance of the patch.

For the moment, there is no uptodate standalone patch file anymore, but only the GitHub repository.

• PHP 6: http://github.com/gron/php-src/tree/PHP_6-traits
• PHP 5.3: http://github.com/gron/php-src/tree/PHP_5_3-traits

For a basic introduction please refer to the RFC (http://wiki.php.net/rfc/horizontalreuse) and the test cases available in the source folder Zend/tests/traits.
