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++
Strings.
They are not interoperable with platform strings, so you end up using std::vector half of the time. The copy policy (copy on write or deep copy) is not defined, so performance guarantees can not be given for straightforward syntax. Sometimes they rely on STL algorithms that are not very intuitive to use. Too many libraries roll their own which are unfortunately much more comfortable to use. Unless you have to combine them.
Variety of string representations
Now, this is a little bit of a platform problem - but I still hope it would have been better when a less obstinate standard string class would have been available earlier. The following string representations I use frequently:
generic LPCTSTR,
LPC(W)STR allocated by CoTaskMemAlloc,
BSTR, _bstr _t
(w)string,
CString,
std::vector
a roll-my-own class (sigh) that adds range checking and basic operations to a (w)char * buffer of known length
Build model.
I am sick to death of all the time spent muddling around with who-includes-what, forward declarations, optimizing precompiled headers and includes to keep at least incremental build times bearable, etc. It was great in the eighties, but now? There are so many hurdles to packing up a piece of code so it can be reused that even moms dog gets bored listening to me.
Hard to parse
This makes external tools especially hard to write, and get right. And today, we C++ guys are lacking mostly in the tool chain. I love my C# reflection and delegates but I can live without them. Without great refactoring, I can't.
Threading is too hard
Language doesn't even recognize it (by now), and the freedoms of the compiler - while great - are to painful.
Static and on-demand initialization
Technically, I cheat here: this is another puzzle piece in the "wrap up code for reuse": It's a nightmare to get something initialized only when it is needed. The best solution to all other redist problems is throwing everything into headers, this problem says "neeener - you cannot".
诚然，其中许多内容超出了严格的语言范围，但在我看来，整个工具链都需要进行判断和发展。
C++:
1:头文件。
链接代码比编译代码更难。同样，模板在翻译单元中包含完整源代码的要求也是荒谬的。在那边的那个文件里。你两秒钟前编译的那个。去那里看看。愚蠢的编译器。
2:空标准库。
我的意思是，是的，在c++ 0x中有std::thread，但没有std::socket或任何类似的东西。没有跨平台代码的主要原因是，您必须为希望在多个平台上执行的每个函数学习一个新的库。没有作为标准提供的OS头文件或OS函数，c++只适合推位。
3:没有多次返回或返回值重载
Double x, int y, char z = func();和void func(double x, int y, char z)一样有效;请。没有返回值重载的唯一原因是我们“可能”编写了模棱两可的代码。可能!请在我真正写出模棱两可的代码时给我悲伤，而不是之前。
4:不反思
可以将反射设置为编译时反射。的确如此。没有任何库使得编写大量的库变得困难，并且严重地惹恼了我。我可以滥用预处理器，但是..
5:在模板上鸭子打字
Yaargh。请，概念和正确的模板错误消息。使用Boost这样的库实际上是不可能的，因为如果你用错了，你就是在瞎猜。
