The APL Interpreter project aims to implement the APL programming language using Haskell, providing insights into both APL's unique features and Haskell's programming paradigms. Users have mixed opinions on Haskell's suitability for this project, citing issues with error handling and performance considerations. Some comments highlight the challenges of managing asynchronous exceptions and the complexity of debugging in Haskell, especially for newcomers. The dialogue suggests that while the translation is innovative, it raises important questions regarding Haskell's efficiency and practicality for performance-critical applications, and the perceptions on whether such an implementation is beneficial or detrimental to users' coding experience.
