类型系统

这里包含类型、数据、结构、算法等软件包，Haskell 主要使用 data 与 newtype 关键字来定义新的数据类型。Type systems are an example of lightweight formal methods（形式化方法）。

Haskell Type Haskell's Data Types! Haskell Algorithms
Haskell Data packages and projects Haskell Data Structures packages and projects
Type Class 类型类首先在 Haskell 中实现对类型类的广泛解释 Haskell Typeclasses vs. C++ Classes
Monad 在 Haskell 中，monad 是一个很重要的类型类，它起源于数学中的范畴论，单体（Monad）可以被看作是各种数据或控制结构的标准编程接口。

包管理

Haskell Platform Included Packages 35 core & widely-used packages
Hackage The Haskell Package Repository
stack Nix integration
cabal
ghc-pkg

cabal-install 支持多个 Haskell 编译器,而 ghc-pkg 仅用于 GHC。

Nix 是一个包管理器，它管理的包环境可信赖、可重现，可原子地执行升级与回滚，在这基础上又有了基于包管理的操作系统 NixOS
haskell.nix 用 Nix 构建 Haskell 包的基础设施，haskell.nix 可以自动将 Cabal 或 Stack 项目及其依赖项转化成 Nix 代码。
