<h2>Richer type hints</h2> HipHop extends the support of type hints to primitive types, like bool, int, and double. It also supports string for type hints.

hhvm/hphp/hack/README.md
# What is Hack? Hack is a programming language for [HHVM](https://hhvm.com) that interoperates seamlessly with PHP. Hack reconciles the fast development cycle of PHP with the discipline provided by static typing, while adding many features commonly found in other modern programming languages. Hack provides instantan...
hhvm/hphp/hack/README.ocpbuild
This document describes an alternative build-system for Hack. This is currently the only build system available on Windows. Meanwhile, this document focuses on using this alternative build system on Linux and OS X; for Windows, see `README.win32`. ### ocp-build, a build system for OCaml applications ocp-build is a bu...
hhvm/hphp/hack/README.win32
We are currently porting Hack and Flow to Windows 64 bits. This document describes the build system, if you want to test the prototype. Be aware that this work will take some time and most tests are currently known to fail. ### Dependency: OCPWin OCPWin is a binary OCaml distribution for Windows. It is self-contained...

For a summary, see the [await-as-an-expression](https://docs.hhvm.com/hack/asynchronous-operations/await-as-an-expression) docs. The guiding principle of “unconditionally consumed with the statement” is to prevent computation from being thrown away. Since we could run the awaits before the statement, if they turn out ...

Status: This is not a full HIP following the usual template/process, but shared as a HIP for external visibility. # Converging constants in Hack and HHVM I’d like to ease a few HHVM restrictions on type constant overriding, and along the way to consolidate the rules around constant inheritance in general. ## Motivat...

hhvm/hphp/hack/doc/HIPs/data_classes.md
Title: Data Classes Status: Draft ## The Problem The Hack runtime does not know which fields are defined in an arbitrary shape, and does not enforce them. It also cannot reorder shape fields, and cannot store them contiguously. This forces the runtime to use data representations that are slower and use more memory. ...
