I'm not aware of any WMF/MediaWiki work being done in Hack yet. Putting Hack into MediaWiki's core would be controversial but a stand alone service/app could easily choose to use it I think. Changing from PHP to Hack only requires changing the opening `<?php` to `<?hh`. Today what Hack gives you is some syntactic sugar for various common idioms from the Facebook internal code base and much stronger typing. The last time I saw someone asking if it was faster on #hhvm the answer was "not yet". Whether strong typing is a pro or a con of Hack vs PHP seems like a religious debate that I'll try to stay out of until the issue is forced. The bits most likely to be of interest in the short term are the `async` and `await` keywords [0] and possibly the Continuation class [1] which makes creating generators easier than the PHP Iterator interface.
