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。

c#:

1)静态方法必须是类的成员

2)静态扩展方法只能添加到静态类中

3)接口函数的实现不会被标记为“override”之类的东西来显示它们来自基类或接口(这使得你很难确保你正在重写你所期望的方法(具有正确的签名))。

我只有3个。我想那很好。

ActionScript / AS3

没有抽象类 没有私有构造函数(所以单例是一种hack) FP10之前没有类型化数组 Flash IDE中的编译/发布时间慢得离谱 内置函数(例如Math)的性能较慢

除此之外,它实际上是一种很好的语言——与流行的观点相反,它比JavaScript好得多,比PHP之类的语言好一百万倍。

C#

Lack of multiple dispatch based on the runtime type of the method arguments. dynamic should solve most of this, but it hasn't been released yet. Interface implementation is declarative not structural. I really like the way Google's Go language is doing types Making asynchronous method calls is really bulky (and I'm pretty sure all threads are OS threads, not lightweight threads) No macro system. I'm not talking about C-style macros here; I'm talking LISP/Scheme style macros Operators are static methods and their signatures are overly constrained (and you can't create new ones).

EL -表达式语言,${…}和#{…JSF 2.0 Facelets用于从底层Java代码中提取数据。

All the fun things, like method calls with parameters and annotation based naming is only present in the EL in Java EE 6 which is only available in Glassfish v3. It is a royal pain to 1) get the right jars for an earlier Servlet 2.5 container, and 2) getting them to work without interfering with any previous implementation available in the container. Having only an earlier version of JSF like 1.2, takes away the method calls and leave you to work with f:setPropertyActionListener - http://weblogs.java.net/blog/2009/07/22/say-sayonara-spal - which, trust me on this, is not very nice. The EL parser has no idea of where the snippet it is to parse and interpret came from, so you tend to give everything an id so you at least can identify which tag made it grumpy. Eclipse gives a warning at every EL method call as it is JSF 1.2. only too.

Haskell(包括所有GHC扩展,而不仅仅是Haskell'98的基础规范)。

我讨厌它的一点是:它不是主流。

C++

(除了lambda函数,我已经避免了Cpp0X中可用的东西)

不强制使用"this"访问成员变量,::GlobalFunction访问全局命名空间。 (更具体地说,算法中缺少lambda函数,将在0x thou中修复)中的所有内容 处理依赖文件/头文件和源文件 基本数据类型上的愚蠢名称(应该命名为uint8, int16等) const_cast功能
