Hooray! I'm a massive fan of HHVM, though not just because it's so fast: Hack is something I'm really interested in. The collections libraries in the stdlib are brilliant to use, and the static typing makes writing some types of code easier and keeps some bugs out of my codebase. The only thing I wish to see is more editor/IDE support for it, so I helped contribute to hack-sublime and have been writing my own plugin for Komodo Edit/IDE. HHVM and Hack were the impetus for me to learn OCaml, which is a lovely language. It's good to see more and more places picking up HHVM, and it's also great to see PHP5.6 and 7 increasing performance drastically, too!
