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)。

Clojure

Lack of built-in syntax for optional and keyword parameters in function definitions. Sure, you can add it easily enough, but that means library writers don't use it. Pervasive destructuring hasn't proven to be a good substitute yet Lack of method combination (before/after/around methods of the sort found in Common Lisp) Too much reliance on Java interop, e.g. there's no built-in file IO Sometimes I want static typing. This one isn't pure hate; I usually prefer dynamic, and attempts to mix the two have been largely unsatisfactory There's no built-in fast binary serialization format for the built-in data structures, though I hear people are working on it

Delphi(又名Object Pascal)，我将讨论本机版本，而不是。net。

Var块! 语言中的接口在设计时就考虑到了COM的使用——因此比c#或Java要复杂得多。ie。涉及引用计数，除非显式禁用它。 没有尝试，只有最终结束; 对象创建过于显式: var obj: TMyObject; .．. obj:= TMyObject.Create; 试一试 .．. 最后 obj.Free; 结束;

而是像这样

auto obj: TMyObject; // compiler adds the default constructor call and the destructor call in a try/finally block. 

好吧，语言太好了，我真的想不出更多，所以我在这里强迫自己:内置类型，如字符串，整数..或者枚举最好有方法。ie。i. tostring代替IntToStr(i)。

Ruby有许多与速度相关的缺陷，但我并不讨厌它们。它也有社区传福音过度的缺陷，但这并没有真正困扰我。以下是我最讨厌的:

Closures (blocks) have 4 different creation syntaxes, and none of them are optimal. The elegant syntax is incomplete and ambiguous with hashes, and the full syntax is ugly. The community tends to be against real documentation, favoring ‘read the code’. I find this childish and lazy. Metaprogramming abuse, particularly in libraries, makes bugs a nightmare to track down. On a related note, pervasive metaprogramming makes a comprehensive IDE difficult, if not impossible, to make. The way block passing to functions is done is silly. There is no reason blocks should be passed outside the parameter list, or have odd special syntax to access (yield). I am of the opinion that blocks should have been given a less ambiguous syntax (or hashes could have used different delimiters; perhaps <> rather than {}), and passing as parameters to methods should have been just like all other parameters. object.method(1, {|a| a.bar}, "blah") These oddities, like the block must be the last parameter passed and passing more than one block is different with longer syntax, really annoy me.

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。

PHP

如果你不能控制服务器，就没有调试功能，即使这样也很糟糕 大量糟糕的PHP代码给所有PHP程序员带来了坏名声 不一致的函数命名 如果我想要一个静态类型变量，就不能有一个静态类型变量(我90%的时间都是动态类型的忠实粉丝) REGISTER_GLOBALS是魔鬼
