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。

objective - c 2.0

严格遵循语言和运行时,而不是库,并且没有任何特定的顺序:

Lack of cVars. No modules. I'm not terribly unhappy with a lack of namespaces, but modules would be nice to have. Ivar-based property syntax requires declarations using the variable name in 3 places. It's fairly hideous. C heritage. Anything to hate about the C language, except for OO and GC, is present. Objects can't live on the stack. Not a problem with Obj-C so much as what it does to programming practices in other languages. I find it strange when I get a return value on the stack in C++, for instance. If I'm not actually looking at the library documentation when I write the code, I'll assume that every function returns a pointer, which often makes for some siginificant cleanup later.

Quenya

• Community is too small. It's next to impossible to get a good language-immersion program going when there's no easy to find another speaker nearby. • Irregular verbs. Yes, I know English and Spanish mentioned them, too, but Quenya was invented. Why does there still need to be irregular verbs? • No Unicode support. I have to have three different Tengwar fonts on my computer before I can read most messages, and several of them are poorly kerned. This wouldn't really be a huge issue given the existence of a Romanized transcription, but Tengwar is so beautiful, you don't not want to use it. • Not all concepts can be easily referenced in Quenya, leading to annoying circumlocutions, or resorting to Sindarin, Númenórean, or (Manwë save me) Klingon to get my point across.

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

我讨厌内梅尔的五个方面:

局部函数不能让步 编译lambda的能力有时取决于它是否内联 元组的值/引用类型语义不一致 数组下标和类型参数之间偶尔会出现歧义 缺乏普遍采用

经过一些思考后重写了这篇文章…

虽然我喜欢PHP,但我讨厌它的五个方面(排名不分先后):

内置函数中的命名和参数顺序不一致。 面向对象的数组方法多亏了SPL,但遗憾的是还没有字符串。 PHP本身没有真正的并发,只有通过托管web服务器的多处理 没有像JavaScript那样的异步调用 只能通过扩展进行操作码缓存。不是很糟糕,只是有点烦人。

这些是令我烦恼的语言特性(或缺乏),但更大的问题是这些与人/社区相关的东西:

事实上,很多使用PHP的人,对编程和良好实践一无所知,从而产生了非常混乱的代码。JavaScript也有同样的问题。 大量的教程/书籍传授了非常糟糕的做法和风格。这可能是第三条的主要原因。 它的坏名声主要是因为第三条和第四条。
