YouTube 就不会存在了. 这是很早以前的事情了.</p><p>现在比如合适的闭包, 变量不变性, 好的异步构思, 等等, 这些是现在的黑客优先考虑的功能.</p><hr><p>不提将来, 长话短说; 这里有一些事情可能让今天的黑客对 Python 3 感兴趣。拿我来<br>说，这些事情引起了我的兴趣:</p><hr><ol><li><p>移除GIL. 或者提供一个更好的异步构思. 也许有可能 Guido 提出 PEP 3156. 类似 Go 的 Channel 这种原语也不错.</p></li><li><p>加速 Python. 认真的说, 如果 Javascript 可能变得更快, CPython 也可以变得更快. 或者 PyPy 成熟到可以成熟到替换它 (应该只有这一个). 如果需要花大价钱或 Lars Bak 可以这么做, 开始动起来把 — 我会作出贡献. 各个大公司也将做出贡献. 会不会是 Dropbox 将会花大代价将 Python 在 LLVM 上面重构?</p></li><li><p>添加更多类型. 那么, 新加入的类型. 让你可以用它来加速一些代码的运行 (就像 Cython), 或提供注解和帮助类型检查(就像 Dart). 给标准库的每一个方法、类都加上类型注解.</p></li><li><p>修改标准库. 让一个团队一起去修改长期的问题, 提高修改速度和修复错误. 提高自己的 API, 然后提供简单、漂亮、常用的接口 (比如 requests vs urllib) 一起加入到标准库里面, 使用命名空间区别. 可以很容易地切换（也许还包括一些自动化工具）。</p></li><li><p>重构 REPL. 现在已经是 2014 年了. 将 REPL 以现代的方式重做. 添加一些颜色. 从 IPython 学习. 做成 Client/Server 的形式, 让 IDE 和编辑器更好的嵌入它.</p></li></ol><hr><p>因此, Python 3 的开发人员, 利用好你们的时间. 好了, 没有太多的时间. 也许, 3 - 4年. 我们已经等了 10 年的 ES6, 我们等它花一半的时间, 然后为你服务.</p><p>它现在并没有让任何人将 Python 3 用到各种地方, 所以需要一定的机会, 打破现在的局面, 尽早发布和交付. 让社区热闹起来.</p><p>你看，Python 3 不是真的杀了 Python. 但是有可能从现在把它拯救出来。</p><hr><p>附：你怎么看？你能想到的东西，另外，你有想到额外的事情可以使 Python 3 中更诱人吗？或者有什么新的特性让你饥渴难耐？</p>]]></content>
