A lightweight library for Object Oriented programming (OOP) in Haskell.
The library is inspired by the "Mutable Objects, with tail-polymorphism" approach as described in the "Haskell's overlooked object system" paper and extends it with:
- Generic up and downcasts using dynamic typing
- An inheritance combinator, from A Denotational Semantics of Inheritance and its Correctness
- Parameterized classes
- CPP macros for deriving parts of the boilerplate
It was created as part of my master thesis "wxHaskell for the web, 2012" where it served as a tool to facilitate the implementation of an object-oriented GUI toolkit in Haskell.
