> Given HHVM is already being dropped from PHP packages because of its lagging compatibility, announcing that they're not targeting PHP compatibility any more might be the nail in the coffin for HHVM (and thus Hack) as a viable “upgrade” from PHP for existing codebases. They're dropping PHP5 support, but it sounds like they're not actively trying to be incompatible with PHP5, so I doubt that gets worse right away. There's no existing codebase that's PHP7 already that would consider Hack, is there?
