Hackett is an experimental, statically typed, pure, lazy functional programming language implemented as a Racket #lang, combining Haskell-style features with Racket's macro system. It is built using the 'Type Systems as Macros' technique and remains a work-in-progress.
Use cases
- experiment with a haskell-like lisp language
- implement statically typed macros in racket
- learn how type systems as macros work
- try bidirectional type inference and typeclasses
- explore lazy functional programming with s-expression syntax
When to choose
- you want to explore typed functional programming inside the Racket ecosystem
- you are researching type-directed macros or type-system-as-macro techniques
- you want to experiment with Haskell features like ADTs and typeclasses in a Lisp syntax
When to avoid
- you need a stable, production-ready language
- you need gradual typing or dynamic typing
- you require complete Haskell compatibility or features like GADTs and type families
