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 / Cocoa / Cocoa Touch:
Lack of namespaces
Difficulty using primitive values with any of the interesting and powerful techniques of Cocoa, e.g., distributed objects, notifications, KVO
Inconsistency with the use of the shortcut dot syntax for accessing properties, often having to use the full length accessors
No GC on the iPhone, and generally GC came rather late to an otherwise highly dynamic language
Inconsistent library support, at least in Cocoa Touch; some very basic things have only recently gotten high level support, e.g., audio handling.
Lack of blocks!
Lua:
I understand the reasons, but seriously. Variables should be local by default, with a global keyword, not vice versa.
I'm in general not a huge fan of the do/end style semantics. I much prefer C-style braces.
Dynamic typing. I know, some of you go "Huh?" but I've been entirely spoiled by knowing exactly what type of data will be in a given variable. Constant if (type(var) == "string") then stuff() end is a pain.
Variables need not be defined before they're used. I would much rather be explicit about what I'm trying to do than risk a typo causing what I like to call "wacky beans".
PHP:
同样，动态类型。
缺少闭包。你可以用$function($arg);但这不算。
同样，变量可以在定义之前使用。我有一个个人策略，总是在使用任何变量之前显式地将其初始化为已知值，并且我将其扩展到我可以控制的任何最佳实践文档。
C / C + +:
头疼=脖子疼。
不支持闭包。(我对c++ 0x很兴奋，因为c++ 0x有这些功能。)
静态类型。“等等，”你说。“你刚才说你不喜欢动态类型!”是的，我确实这么说过。但是静态类型也会让人头疼。(如果有选择的话，我仍然会选择静态类型。)最理想的情况是，我希望语言默认是静态类型的，但也支持动态类型。(我还想要一匹小马，500亿美元，还有整个世界。)
