为什么要柯里化（why-curry-helps）slide http://git.io/why-curry-helps 📈

还记得 Haskell Curry吗，

多巧啊, 人家姓 Curry 名 Haskell, 难怪 Haskell 语言会自动柯里化, 呵呵. 但是不奇怪吗, 为什么要柯里化呢. 为什么如此重要导致 Haskell 会默认自动柯里化所有函数, 不就是返回一个部分配置好的函数吗.

我们来看一个 Haskell 的代码.

Modified Python Dotdictify
# turn dict into an object that allows access to nested keys via dot notation
# from http://stackoverflow.com/questions/3797957/python-easily-access-deeply-nested-dict-get-and-set
# made three modifications:
# --added `get()` method
# --added `if not dict.__contains__...` to `__contains__()`
# --can now accept None as key
