Use GADTs and type classes for Haskell domain modeling to enforce type safety and purity. This approach provides structured guidance and practical examples to help you apply these advanced patterns for composable, correct code.

The best way to manage effect systems in Haskell is through effect layering to maintain pure cores and explicit effect boundaries. This approach demonstrates patterns for clean, testable, and composable code that safely models effects.

Structure a Haskell project to preserve purity by separating pure domain logic from effect boundaries using type classes. This approach delivers design principles and starter projects that enforce explicit effects for safe, composable code.

Yes, you can use Haskell type classes for modular architecture in correctness-critical systems. This approach provides concrete examples of safe error handling and domain modeling to ensure correctness through strict type enforcement.

A limitation of using GADTs in Haskell domain modeling is the increased complexity in the advanced type system. This approach helps overcome the steep learning curve by providing structured guidance from basic to advanced usage examples.
