我讨厌内梅尔的五个方面:

局部函数不能让步 编译lambda的能力有时取决于它是否内联 元组的值/引用类型语义不一致 数组下标和类型参数之间偶尔会出现歧义 缺乏普遍采用

Ruby:

太慢了 自负的群体 这不是闲谈 在nil上调用方法时出错，而不是返回nil à la Objective C 非线程

C#

我对c#非常满意，但这两个真的让我很恼火:

Constructor-based initialization for immutable classes is less convenient, less intuitive (when you read the code you don't understand what you assign to what), has less IDE backing than inline object initialization. This makes you lean towards mutable classes inevitably. I know this has been mentioned before, but I strictly have problems with initialization syntax for immutable classes. switch is too verbose. Whenever I see a situation where a switch would be proper, I'm really inclined to use an if..else if.. just because it's more terse (~30% less typing). I think there should be no fallthrough for switch, break should be implied, and case should allow comma separated list of values.

帕斯卡对象:

There's a lot of jumping back and forth in the file you're editing since the interface and implementation are split into two parts but still jammed into the same file. Dynamic indexing of arrays, strings start at 1, you specify the starting index when declaring fixed arrays and dynamically allocated arrays always start at 0. Classes and objects (not to speak of interfaces) are bolted on top of the language and among other things can't be stack allocated like records can. When calling functions without parameters the () are optional, leading to a lot of pain when you are dealing with function pointers or trying to refer to the result of a function using the function name. Parameter lists can't handle fixed array types or function pointer types without external type definitions.

这仅仅是一种语言，一个标准库的遗憾借口，而脆弱的IDE应该有自己的列表。

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)。

Lua:

元表是如此令人困惑，直到他们“点击” 缺少像a += 20这样的赋值操作符是一种痛苦 没有集成的面向对象的解决方案意味着每个人和他的狗都使用自己的口味 用于注释(——)的语法排除了加/减前后操作符的可能性 不入侵C端就不可能有任何先发制人的多任务系统
