不得不假设我们有语言。我们做什么?

德尔菲:

IDE有点不稳定。 代码洞察有时令人困惑。 调试有时是有bug的。 更新多个项目文件可能会很麻烦。 如果启动时一个或多个包不可用，错误消息会弹出几次。

我觉得最喜欢的语言是不可能选择的。动态类型和静态类型不能进行比较，所以我只列出我使用的是哪一种类型

C++:

Template metaprogramming syntax is ugly. An implicit ::value would make it much more concise ->. Why can't the compiler figure out that I'm doing a ptr.thing and just do -> for me? I hate whitespace. So the whole vector<vector<int>> has to be vector<vector<int> > makes me get the jitters and then I can't focus whenever I see that line of code and I end up trying to figure out a way to use int[][] or something Macros. I personally love the concept of macros. But with C++, I that the system is a hack I'm a hater of ;

Python:

字符串是不可变的。这样我就不能用string[4]="b" 通过引用隐式复制列表。哪个泄漏到[[0]*width]*height问题 缺少尾递归(每当我输入错误递归函数时，我必须安装IDLE以避免吐出1000条错误消息) 字典键不接受列表/字典 缺乏深度范围。当我做一个列表推导时，我不希望其中的变量影响到外部作用域

The behavior AndAlso / OrElse and And / Or seems backwards. Perhaps they should be switched. When can only be used for exception catching. The ability to do a When conditional would be nice for some other things. There is no friggin Refactoring in the VS IDE (not really the language's fault) like there is with C# Not <obj> Is Nothing. Yes, this has been remedied by IsNot, but for some reason I see the Not Is being used too often. (I see it much more frequently with devs who speak english as a second language, does it make better sense from that angle?) It doesn't require the () on ToString() and most functions. (Leads to sloppy coding habits) Having to do _ when breaking a line. It allows optional parameters. (Leads to sloppy coding habits) declaring an array is done by UpperBound and not by capacity. "Dim arr(2) as String" will actually hold 3 elements. Having = be a comparison and assignment operator.

C#

c#最让人讨厌的是:

(1)事件具有对所有侦听器的强引用，从而防止了侦听事件的任何东西的垃圾收集。如果你想看到这造成的问题，只需在网上搜索所有试图通过创建某种“弱引用事件处理程序”来解决问题的人。

(2)在调用一个事件之前，需要检查它是否等于null，这似乎应该由语言来处理。

(3) XML序列化器无法读取/写入XML文件中的注释。在手工修改XML文件和用c#编写的工具修改XML文件的环境中，情况并不好。可以通过使用原始的XmlDocument来解决，但如果能够将其抽象到一个类中会更好。

(4)构建过程不允许您直接访问xsd文件之类的东西，相反，您需要一个中间步骤，即创建一个c#部分类。这也会导致XAML文件出现问题，有时需要重新构建两次才能使更改正确地通过。

(5)不支持CPU intrinsic，如MMX和SSE 1,2,3,4，因此这些有价值的CPU特性在运行c#应用程序时无法使用。

其他没有进入我的前5名:

(6)不能将字段标记为属性，所有属性必须从一开始就显式地实现:

目前有:

public class MyClass {
    private int someInt;

    public int SomeInt {
        get {
                return someInt;
        }
        set {
                someInt = value;
        }
    }
}

想

public class MyClass {
    [IsProperty(public, get, set)]
    private int someInt;
}

(7)不支持多个返回值，例如:

public int, string, double MyFunction()
{
    ....
    return x,y,z;
}


public void TestMyFunction()
{
    int x, string y, double z = MyFunction();
}

(8)不支持协变返回类型

我对泛型实现有一些不满，但我就此打住。我认为c#是一种很棒的语言，可以完成所有的GUI、网络和配置管道，并且是我的首选语言，可以以一种可以长期支持的方式快速启动和运行。

C++

cryptic error-messages when templates are involved lack of template constraints (many cases can be worked around with template metaprogramming, but this will result in unreadable code (at least for average programmers) in most cases) pointer to member-function syntax c++ standards committee should release offical standards more often (or at least release separate updates to the standard library itself), i mean really TR1 was released 2005, and we still dont have a shared_ptr, bind and alike in the standard library. -
