Haskell，一门通用型纯粹函数式编程语言。其特性有：静态类型，高阶函数，多态，型别类，以及单子式副作用等。Haskell编译器几乎在每一种计算机上都可以运行。
C++11的Concepts、C#的LINQ、Java中的泛型、Scala、CoffeeScript、F#、Python、Swift 等语言都从中受到启发和得到灵感。
Haskell在工业界有不少应用，最集中的是在金融界的高频交易。

安装
OS X
OS X安装包安装后，会创建：
/Library/Frameworks/GHC.framework /Library/Haskell
运行 /Library/Haskell/bin/activate-hs
Haskell now set to: GHC 7.10.2 Arch. x86_64 Platform 7.10.2-a
运行 /Library/Haskell/bin/cabal
/Users/huihoo/.cabal/config /Users/huihoo/Library/Haskell/bin
vim ~/.bash_profile
export PATH="$HOME/Library/Haskell/bin:$PATH"
指南
输入ghci进入GHC交互模式
ghci> [2,4..20] [2,4,6,8,10,12,14,16,18,20] ghci> [x * 2 | x <- [1..10]] // 列表推导式(list comprehension) [2,4,6,8,10,12,14,16,18,20] ghci> [x | x <- [10..20], x /= 13, x /= 15, x /= 19] // 多个谓词(predicate) [10,11,12,14,16,17,18,20] ghci> [0.1, 0.3 .. 1] [0.1,0.3,0.5,0.7,0.8999999999999999,1.0999999999999999] ghci> [x | x <- [50..100], x `mod` 7 == 3] [52,59,66,73,80,87,94]
