从程序人生-elixir：灵丹妙药？or 徒有其名？上看到这个库，那就从这里开始学习elixir吧。

github地址

说明

这个库干了一件暴力的事情，把wikipedia的最新词库导入，使用macro在编译时生成近10,000个按词进行正向最大匹配的递归函数，这样来完成简繁体转换，编译一下要40分钟左右，但是性能超好：

$ mix bench
Settings:
  duration:      1.0 s
  mem stats:     false
  sys mem stats: false

[20:49:22] 1/8: ChineseTranslationBench.translate a character t->s

好吧，开始阅读代码玩一玩。
