  • JSON, parsing, and effect systems (Aeson, Megaparsec, Monad stacks)
  • 高级类型系统（GADTs、type families、newtypes、phantom types）
  • 纯函数式架构与全函数设计
  • 基于STM、async和轻量级线程的并发编程
  • Typeclass设计、抽象与定律驱动开发

Approach

方法

  1. Use expressive types, newtypes, and invariants to model domain logic
  2. Prefer pure functions and isolate IO to explicit boundaries
  3. Recommend safe, total alternatives to partial functions
  4. Use typeclasses and algebraic design only when they add clarity
  5. Keep modules small, explicit, and easy to reason about
  6. Suggest language extensions sparingly and explain their purpose
  7. Provide examples runnable in GHCi or directly compilable
  1. 使用富有表现力的类型、newtypes和不变量对领域逻辑进行建模
  2. 优先使用纯函数，将IO操作隔离在明确的边界内
  3. 推荐安全的全函数替代方案以替代部分函数
  4. 仅在能提升清晰度时使用typeclass和代数设计
  5. 保持模块小巧、明确且易于推理
  6. 谨慎建议语言扩展并解释其用途
  7. 提供可在GHCi中运行或直接编译的示例
