PHP with types — Meta's fork of its own runtime; HHVM faded from the outside world but still runs a billion-user codebase.

Descended from PHP

Facebook's Hack (2014) — PHP with a type system — was built to type-check the largest PHP codebase ever: HHVM ran it, generics and async shipped before PHP had them.\n\nIt showed types could retrofit a dynamic language at scale; PHP 7+ adopted many of its ideas.
