The Simple Secret Behind Effect’s Power

In this video, we break down the complexities of effect systems, focusing on the core concept of 'thunks'—nullary functions that encapsulate computations. We address two main barriers to adopting effect systems: perceived complexity and unclear value proposition. Through practical examples, we implement various combinators like 'repeat,' 'retry,' and 'timed,' demonstrating the power of maintaining computational blueprints. Finally, we explore composition operators and a generator syntax for sequential programming, illustrating the simplicity and potential of effect systems. 00:00 Introduction to Effect 01:02 Understanding Thunks 04:10 Implementing Repeatability 07:39 Exploring Retryability 09:46 Aroundability: Instrumenting Effects 14:29 Effect Composition and Sequencing 17:40 Conclusion and Final Thoughts
