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。)

我讨厌所有语言的五件事(至少就我所知):

Does what I say/type, not what I mean Will undoubtedly meet people who think they are experts in the language, but just make a mess of it (e.g. people who insist that removing comments/unused local variables will speed up execution time for a program) Unless the language is obsolete, then it will probably continue to evolve (either the actual language, or the concepts behind using it effectively) requiring you to actively develop with it so as to not fall behind. Can't modify the lexer/compiler (add in own context sensitive grammar) No perfect language (every language is missing some sort of useful feature that usually is either impossible to simulate, will unavoidable have an ugly interface or just require far too much time to implement and get it right)

C#

I wish I could switch() on any type, and that case could be any expression. Can't use object initializer syntax with 'readonly' fields / private set autoprops. Generally, I want language help with making immutable types. Use of {} for namespace and class and method and property/indexer blocks and multi-statement blocks and array initializers. Makes it hard to figure out where you are when they're far apart or mismatched. I hate writing (from x in y ... select).Z(). I don't want to have to fall back to method call syntax because the query syntax is missing something. I want a do clause on query syntax, which is like foreach. But it's not really a query then.

我真的到达这里了。我认为c#非常棒，而且很难发现它有什么缺陷。

Haskell:

惰性计算导致空间泄漏。 数字层次结构不是根据数学抽象构造的。 严格的单元IO会使调试更加困难。 大型实现处理I/O的方式似乎与标准不太兼容。(特别是，输出字符只输出低8位——然后构建代码，使用这个假设来执行二进制I/O。我吐!) ($)运算符的结合性可以被改变以使某些表达式更漂亮。

大多数问题都不会上升到讨厌的程度，有些人试图解决或为每一个问题构建可靠的变通办法。

编辑:关于第5点有些困惑。特别是有些人似乎认为我指的是论证的顺序，但我不是。我不解释我的意思，我只想让人们去下面的链接http://hackage.haskell.org/trac/haskell-prime/wiki/ChangeDollarAssociativity，它很好地表达了我的意思。

JavaScript

数字作为字符串-数学可以 数字令人沮丧 解释为字符串。5 + 2 = 52? 叽阿… 权限-所有最好的东西都需要用户的权限! 屏幕更新—浏览器必须处于稳定状态才能更新屏幕。似乎没有一种方法可以强制在脚本中间更新屏幕。 慢-虽然谷歌的Chrome很好… 浏览器的差异使语言的使用[审查]。

C++:

缺乏象征意义。 过度迷恋C语言的兼容性。 极其复杂的预处理器。 模板错误几乎是不可理解的。 没有垃圾回收。
