I agree with you to a certain degree, PHP and Hack should not diverge =
but (kind of <b>but</b>)...
IMO Hack made a wrong language design decision and I do not see why PHP =
should make the same mistake. And I am sure, Hack would catch up quickly =
if PHP would decide to put all types on the right (as in the return type =
hint RFC - just as an example).
