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是我最喜欢的,但也很糟糕。

It has the worst pre-processor ever. Why didn't they use something like m4? The whole header vs source file model is broken. Pascal got it right with units. It needs case ranges in the switch statement. Unions and casts from void* break the type system. This makes garbage collectors impossible. No nested functions. GNU C has this, but it should be standard. No boundary checking for allocated memory. There are tools that discover this but they don't detect errors where a piece of code miscalculates an address and writes to an allocated region which isn't related at all. I hate the whole pointer arithmetic. No bounds checking for arrays. Too many issues regarding portability. Even wchar_t differs across platforms.

C#

我对c#非常满意,但这两个真的让我很恼火:

Constructor-based initialization for immutable classes is less convenient, less intuitive (when you read the code you don't understand what you assign to what), has less IDE backing than inline object initialization. This makes you lean towards mutable classes inevitably. I know this has been mentioned before, but I strictly have problems with initialization syntax for immutable classes. switch is too verbose. Whenever I see a situation where a switch would be proper, I'm really inclined to use an if..else if.. just because it's more terse (~30% less typing). I think there should be no fallthrough for switch, break should be implied, and case should allow comma separated list of values.

关于c#:

I hate that there is no keyword to specify which exceptions are thrown from a method like in java. Its a much better way to document exceptions than using an XML comment. I would also want a much better syntax for generic constraints like oring and anding of constraints. Why a method can't return more than one value? Lack of support for aspect oriented programming in the language. Why can't you annotate each one of the property accessors with an attribute? Lack of builtin regexp support like in perl.

我的母语……虽然它听起来比克林贡语更美,但它是一个语法地狱……

conjugations: even regular verbs have different forms for each person and time (with few exceptions)... Example: I see, you see, he/she/it sees, we see, you see, they see translates into: Ich sehe, du siehst, er/sie/es sieht, wir sehen, ihr seht, sie sehen. polite form of address: equals 3rd person plural, used to equal 2nd person plural in the middle age... I really hate the concept of distinguishing between "Du" and "Sie" for my philosophy is that each human being should be considered equal in the amount of respect for it deserves (I mean, what are swear words for, hm?) punctuation: show me a language that uses more commas regularly! missing suitable words: eg. there's no real German equivalent of "convenience" or any derivate of this word... in almost every case you just can't translate it into another German word and keep the meaning... instead you would have to make up a whole subset to describe it somewhat adequate... Anglicisms and Denglish: Sure, the English language has "Kindergarten" or "Poltergeist" and what not but the German language is overflowing with Anglicisms nobody needs... Even worse: We redefine some words we adopt, eg. in German "Handy" means a cell phone and has nothing to do with the adjective it is in English... There are influxes on grammar as well, leading to "Denglish" expressions (see linked article at Wikipedia) There's more, but I don't want to exaggerate this and those are my personal Top5 of what I hate about the German language...

到目前为止,我最讨厌我最喜欢的语言的地方是我的选择总是在变。每次我以为我找到了命中注定的那个人,我就会发现我讨厌他的5个(或更多)地方。然后那边的草看起来更绿……
