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。

我讨厌c++的五个方面

联系时间。使用分布式构建，我可以在同一时间重新构建我们的整个项目，它需要我们的链接器运行。 没有防止内存操作重新排序的标准方法。使用写组合内存通常需要滥用volatile关键字。防止读重排序(在处理SIMD数学管道时通常是优化的关键)通常是通过在例程中间注入空ASM块来实现的。 多步宏来解决字符串化问题:

#define STR_LINE2(x) #x
#define STR_LINE(x)   STR_LINE2(x)
#define LINE_NUMBER STR_LINE(__LINE__)

做字符串操作通常是很痛苦的。 大量的非标准化printf变体(vsnprintf_s vs _vsnprintf_s)。

C#.

我最讨厌的是:

No multiple inheritance - imagine you could provide whatever GUI framework base class (Control, Window, whatever) with MVC - related stuff, etc... framework / base class agnostic! No "friend" keyword... I know, the RAD - victims would abuse it for all kinds of stinky code and for hilarious malpractices, but it would be nice for the OOD - guys to enforce the law of demeter No language integrated DBC features, there are the Contracts, but I would rather have that Spec# - style with a general purpose "!" - postfix operator No AOP (I don't get it... this language has attributes, it would have been SO EASY to add interception code in the compiler!) No weak event delegates - the observer pattern becomes nothing but a memory leak bait as it is now... :-(

SAS

从不有自己的想法(一切都是借来的)。 贪婪于庞大的数据集。 使用Java，但从未学习过什么是对象。 窃取Perl，但将其隐藏在其数据步骤中。 统计学家总是撒谎!

Haskell

Sometimes the type system feels backwards. What if I don't want the compiler to infer types for my variables? What if I want the opposite, where it does constraint checking on said variables? For example, instead of inferring the type of the elements of a list, it instead makes sure that they all belong to a particular typeclass. This is a subtle but huge difference that makes it difficult for me to program UIs. It can be done, but it takes more effort than it does in some other languages. Haskell rocks for the non-UI parts, but the UI I leave to an untyped language. Allowing the construction of infinite values leads to some really frustrating errors sometimes. NoMonomorphismRestriction. Bytestring handling bites me in the ass sometimes and you don't know it until your program crashes because you mixed them up improperly. Something is wrong here, when we are losing type information that should have prevented this. Typeclasses should be automatically derived for trivial cases, like witness types, but there's a strong potential for abuse there.

C

字符串处理 内存管理(决定谁应该分配内存，谁应该释放内存) 没有名称空间(最大的) 标准库中没有列表/数组和其他基本DS

JavaScript

使用不带var的变量会自动使其成为全局变量 分号不是强制性的 比较运算符“==”和“===”以及它们用法上的混淆 没有适当的支持来处理二进制数据 再一次. .没有命名空间 变量没有块作用域。(来自C世界的人很讨厌)
