I love PHP, and I'm sad by what FB did with HHVM (taking away PHP support too soon), but I do want to encourage folks to give HackLang a try. There's a lot of what PHP devs are asking for in that dialect already, and the potential of that language shouldn't be underestimated.
@pollita How does it compare with PHP nowadays? I read that after PHP7 the game is not worth the candle as the performance of PHP has overcome HHVM. Quick finding about that matter: https://www.wpoven.com/blog/hhvm-vs-php-7-performance-showdown-wordpress-nginx/

@phaberest I'm not sure of exactly figures, but I believe they're "mostly equal" in terms of perf. Certainly not the 2:1 difference from PHP5 days.

The syntax of HackLang is just better from top to bottom though. It's HackLang that HHVM has going for it today.

@pollita All in all I'm happy to see that PHP in general is sort of coming back to life, it looked dead for long time while other things like Node, Typescript and Python were taking the spotlight. I'll play with HHVM and give it a chance, thanks for mentioning it and remember me about it!
