程序设计的美学都在这里了。
贴一小段笔记：
Data Structures:
nil: nil
char: \c or (char c)
number: 1 or (num 1)
string: "abc" or (str abc) ???
keyword: :a or (keyword "a")
symbols: 'a or (quote a)
boolean: false or (boolean false)
list: '(1 2 3) or (list 1 2 3)
vector: [1 2 3] or (vector 1 2 3)
hash: {:a 1, :b 2} or (hash-map :a 1 :b 2)
set: #{1 2 3} or (hash-set 1 2 3)

发文前在本地打底稿多么地重要！
来到 ruby 的地盘打广告，当初不少忽悠 java 到 ruby 的，现在忽悠 ruby 到 clojure，还有一个 scala 怎么比较少的人忽悠。我是正在学 clojure。
正在看 korma, 感觉有 sqlalchemy 的潜力
(select :users (fields :id :employees.name)
(join :employees (= :users.employee_id :employees.id)))
#13 楼 @fastzhong
本来 2.10 release 那天想发个类似的系列贴介绍介绍的，不过好像有人开始不满了也就没去弄了 XD
而且个人感觉 Scala 开始向一个 奇怪的方向发展了，也越来越复杂了：加入了 类似 method_missing的 applyDynamic 方法，加上新的反射机制揉出一个 Scala 元编程，又不知为何加入了 Macros。引用 Twitter 上面某人的话："because none of these pepole are writing code for money. "。
不过，2.10 引入了 AKKA 的异步算子（Future），11 年等到现在总算是来了:）若果再有 Dataflow 那就更好了。

#22 楼 @James_Zhan 好吧，clojure 的语法确实舒服，学会了什么 clojurescript，rouge。。。scheme，common lisp 都搞定了。
