Algebraic Effects for the Rest of Us | Hacker News

A Hacker News thread unpacked what algebraic effects are and how they differ from ordinary effects and resumable exceptions.

Commenters debated whether effect systems really improve type-safe control flow, dependency injection, and async programming.

OCaml 5, Rust, React hooks, and the Haskell library Bluefin came up as practical examples or alternatives.

The discussion framed effect systems as a potentially useful design tool with implications for OCaml, Rust, Haskell, and JavaScript frameworks.
