Hi!
Other tools we are using, such as Phabricator, will
also be following HHVM
to Hack (presumably).
I am not sure this is the case. Mozilla recently declared they want to
use Phabricator[1], but I heard no mention about HHVM. Which makes me
think that one stays on PHP. Also, Phabricator is now independent from
Facebook, afaik, since it's developers have separate company, Phacility.
