最近Stack Overflow上有一群讨厌perl的人,所以我想我应该把我的“关于你最喜欢的语言你讨厌的五件事”的问题带到Stack Overflow上。拿你最喜欢的语言来说,告诉我你讨厌它的五件事。这些可能只是让你烦恼的事情,承认的设计缺陷,公认的性能问题,或任何其他类别。你只需要讨厌它,它必须是你最喜欢的语言。

不要拿它和其他语言比较,也不要谈论你已经讨厌的语言。不要用你最喜欢的语言谈论你喜欢的事情。我只是想听到你讨厌但能容忍的东西,这样你就可以使用所有其他的东西,我想听到你希望别人使用的语言。

每当有人试图把他们最喜欢的语言强加给我时,我就会问这个问题,有时是面试问题。如果有人找不出他最喜欢的工具的5个缺点,那他对它还不够了解,不能提倡它,也不能利用它赚大钱。他还没有在足够多的不同情况下使用它来充分探索它。他把它作为一种文化或宗教来倡导,这意味着如果我不选择他最喜欢的技术,我就错了。

我不在乎你用什么语言。不想使用特定的语言?那就不要。你通过尽职调查做出了明智的选择,但仍然没有使用它?好吧。有时正确的答案是“你有一个强大的编程团队,有良好的实践和丰富的Bar经验。改成Foo是愚蠢的。”


This is a good question for code reviews too. People who really know a codebase will have all sorts of suggestions for it, and those who don't know it so well have non-specific complaints. I ask things like "If you could start over on this project, what would you do differently?" In this fantasy land, users and programmers get to complain about anything and everything they don't like. "I want a better interface", "I want to separate the model from the view", "I'd use this module instead of this other one", "I'd rename this set of methods", or whatever they really don't like about the current situation. That's how I get a handle on how much a particular developer knows about the codebase. It's also a clue about how much of the programmer's ego is tied up in what he's telling me.

憎恨并不是衡量人们了解多少的唯一尺度,但我发现它是一个相当不错的尺度。他们讨厌的事情也让我知道他们对这个话题的思考有多好。

Ruby:

重要的空白。对于解释器,行尾=语句的结束,除非看起来语句应该继续(或者显式转义换行符)。 慢 在线文档不如Python的好(为了辩护,Python的很棒) 我刚才提到慢了吗?

其他回答

我不敢相信,我最讨厌的Python竟然还没被提到:

(Prior to 3.x) Relative imports look like absolute imports. import foo Does this import foo from the directory you're standing in or from the sys.path? Zipped eggs, leading to a sys.path full of shite. Zipped eggs means you can't use grep and find (to among other things debug problem 1)! Fortunately, there's pip. Use pip. Some of the included batteries are unpythonic. It grates to use them. Might be the fault of distro's and packagers, but still: sourcefile-encoding set to fscking ASCII on install/compile. WTF? Means I have to put the "# coding: UTF-8"-stuff in every single .py I ever make.

Py3k解决了我的其他几个讨厌的问题,例如坚持字符串是unicode的,8位的东西是不同的……

Emacs Lisp

目前还没有足够的商业市场让人们全职用elisp编码 GNU Emacs vs XEmacs不兼容 Scheme中的嵌套函数很整洁,我希望elisp有[1]的概念 用于简单遍历列表的do循环或其他一些工具不是标准的(当然,您现在可以使用lambda进行映射)[1] (function (lambda(…)))[1]应该有一个简写

当然,Lisp的一个美妙之处在于,用一行代码在你自己的代码中修复这些问题并不难。但这并不是与生俱来的,这让我很恼火。

好的问题;我有点不好意思,因为我想不出更好的东西来恨,但说实话,法官大人,没什么好恨的。

德尔菲:

IDE有点不稳定。 代码洞察有时令人困惑。 调试有时是有bug的。 更新多个项目文件可能会很麻烦。 如果启动时一个或多个包不可用,错误消息会弹出几次。

c# / .net:

Classes should be sealed by default There should be no lock statement - instead, you should have specific locking objects, and there should be methods such as Acquire which return disposable lock tokens. Corollary: there shouldn't be a monitor for every object. GetHashCode() and Equals() shouldn't be in System.Object - not everything's suitable for hashing. Instead, have an IdentityComparer which does the same thing, and keep the IComparer<T>, IComparable<T>, IEqualityComparer<T> and IEquatable<T> interfaces for custom comparisons. Poor support for immutability Poor way of discovering extension methods - it should be a much more conscious decision than just the fact that I'm using a namespace.

这些都是我想出来的,明天问我,我会想出一个不同的5个:)

PHP:

人们永远无法确定某些几乎常见的扩展在所有web服务器上都可用。 试图成为未来的一切(goto,闭包,…) 对于没有经验的用户有很多安全风险 更多的操作符重载会很好 所有不学习如何使它正常工作的可怜的程序员,给它一个坏名声

尽管如此,PHP是(脚本)语言。: -)
