Indeed - type hints can be quite useful, though hiphop is smart enough to
figure out it will be an integer return from code :)
It is quite interesting to see the enhancements to PHP that have been inside
facebook and now are all released - XHP evolves PHP syntax to fit the web world
(
http://www.facebook.com/notes/facebook-engineering/xhp-a-new-way-to-write-php/294003943919
), the XBOX thing allows background/async execution of work without standing
in the way of page rendering, etc.

Well, the build itself is quite portable (you'd have to have single binary and
LocalSettings.php ;-)
Still, the decision to merge certain changes into MediaWiki codebase (e.g.
relative includes, rather than $IP-based absolute ones) would be quite
invasive.
Also, we'd have to enforce stricter policy on how some of the dynamic PHP
features are used.
I have to deal here with three teams (wikimedia ops, mediawiki development
community and hiphop developers) to make stuff possible.
Do note, getting it work for MediaWiki is quite simple task, compared to
getting it work in Wikimedia operations environment.
What I'd like to see though as final result - MediaWiki that works fine with
both Zend and HPHP, and Wikimedia using the latter.
Unfortunately, I will not be able to visit Berlin developer meeting to present
this work to other developers and will try to get some separate discussions.
You know, most of work will be coming up with solutions that are acceptable by
Tim :-)

My findings are hectic, at the moment, and I don't want to talk too much about
them, until I get decently working mediawiki.
BTW, Main_Page and Special:BlankPage were both served in ~12ms. Now I have to
get complex parser test cases work, and such.
