✨ This keynote talk was recorded at Lambda Days 2024. Join our Waiting List for 2025 and be part of the event next time! https://lambdadays.org ✨ Abstract Algebraic effects and handlers are a powerful way to incorporate effects in programming languages. Algebraic effect handlers can express any free monad in a concise and composable way, and can be used to express complex control-flow, like exceptions, asynchronous I/O, local state, backtracking, and many more. However, existing designs of algebraic effects often require effects to be executed sequentially. In this talk, I give an overview of algebraic effect handlers, and discuss how to combine effect handlers with parallelizable computations. Let's keep in touch!
