Publisher's Synopsis
Level up with Haskell's most powerful abstractions:
✨ Monads and applicatives - Conquer side effects and context-aware code.
✨ Generalized Algebraic Data Types (GADTs) - Enforce invariants at compile-time.
✨ Dependent types - Blur the line between types and values.
✨ Abstract algebra in practice - Monoids, groups, and rings in your editor.
For intermediate Haskellers craving depth, this book blends rigorous theory with battle-tested patterns.
