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!
哇，我很惊讶SQL还没有出现在这里。我猜这意味着没有人喜欢它:)
跨实现的语法不一致
细微的代码差异可能会因为看似模糊的原因而产生巨大的性能影响
对文本操作的支持很差
入门成本低，但掌握这门语言的学习曲线陡峭
最大限度地标准化社区的最佳实践，这包括语法风格。
.．.还有一些额外的讨厌它的理由，不需要额外收费
the WHERE clause goes last, making it easy to prematurely execute an UPDATE or DELETE, destroying the whole table. Instead, the WHERE should go somewhere up front.
It's difficult to implement relational division.
I can set a value to NULL, but I can't test it for equality with NULL. I can check IS NULL, but that just complicates code -- needlessly so, in my opinion.
Why do we need to completely respecify the formula for a GROUPed column, rather than setting an alias on the column and then GROUP BY the alias (or column index as with SORT)?
我是在冒险，因为我不能全职使用它，但无论如何我会尝试一下!
Perl 6
func("frew") != func ("frew")
It annoys me, but there is good reason for it. In Perl 5 print (5 + 6) * 10 still gets me every now and then
It may be easier to parse than Perl 5 in a lot of places, but it still kills my editor sometimes
It still has a lot of the line noise Perl 5 which scares a lot of people. That means it's harder to get them excited etc.
There are no libraries yet.
This will be a non issue if Perl 6 does indeed end up supporting Perl 5, but that may be a burden not worth bearing.
There's no REPL, or what rubyists would call irb.
A solid interactive Perl 6 with tab completion, color coding, etc, would make using and learning it so much nicer.
Currently the documentation is basically the English spec. Not exactly an easy read.
I know it's a stupid cliche, but it's not out yet!
(I am allowed to complain because I am helping :-P)
前三点是语言;剩下的并不是语言本身，而是它还没有问世的事实。
