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。

我讨厌Java(目前它是我最喜欢的语言)的五个方面,排名不分先后。

As much as I am a fan of Java Generics, there are a lot of oddities that arise from the way it was designed. As such there a myriad of annoying limitations with generics (some of which are the result of type-erasure). The way Object.clone() and the Cloneable interfaces work is totally broken. Instead of taking the high-road and making everything an object (a.la. SmallTalk), Sun wimped out created two distinct categories of data-types: Objects and primitives. As a result there are now two representations for fundamental data types and wierd curiosities such as boxing/unboxing and not being able to put primitives in a Collection. Swing is too complex. Don't get me wrong: there's a lot of cool stuff one can do with Swing but it is a great example of over-engineering. This final complaint is equally the fault of Sun and those whom have written XML libraries for Java. Java XML libraries are way too complicated. In order to simply read in an XML file, I often have to worry about what parser I am using: DOM or SAX? The APIs for each is equally confusing. Native support in the language for easily parsing/writing XML would be very nice. java.util.Date sucks. Not only is it unnecessarily complicated but all the useful methods have been deprecated (and replaced with others that increase complexity).

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...

标准库的奇怪之处:它并不总是显示最佳实践,而且文档不足 硬编码FunctionX, TupleX类 缺乏属性:getter和setter是分开的,这违反了DRY,并且使得像FRP这样的事情几乎不可能实现 需要= _来初始化属性

TCL

这是我最喜欢的语言,几乎可以做任何事情。多年来,它已经(慢慢地,非常缓慢地)演变为解决大多数让我烦恼的事情。而且这门语言非常灵活,很容易实现语法来覆盖那些仍然困扰我的东西。但是语言中有一些东西是不能轻易改变的,只是打破了它的禅意:

Arrays (of the associative kind, what Perl calls hash) don't have proper value semantics. This makes them awkward to pass to and return from functions. Also, this means that they can't be nested. For this reason dicts (dictionaries) were invented but too late, the nice array access syntax: $array($foo) is now forever taken by stupid arrays for backwards compatibility. We're now stuck with: dict get $dict $foo which is much more verbose and to me feels less readable. No real closures. Though it can be emulated somewhat by globals or namespaces but that defeats the reason for closures in the first place. Although, I can't really see for now how closures can be implemented in a pure value semantics system. Teacup is hard to use and is not at all intuitive compared to all other repository tool out there. This is more ActiveState's fault than tcl-core and doesn't really break tcl's Zen when coding but it is still very annoying.

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。
