Compares effect libraries for Scala and shows how Keyo implements algebraic effects while contrasting design choices in Cats Effect and ZIO. Demonstrates concrete examples based on Keyo that model side effects, asynchronicity and failures using type constructors, explains the “secret sauce” that lets those abstractions represent real‑world domain operations, and highlights practical differences in error handling, composability and runtime behavior observed in the examples.
