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

C++

太容易随机破坏内存并创建几乎不可能找到的错误(尽管Valgrind在修复这个问题上走了很长的路)。 模板错误消息。 在使用模板时，很容易将所有内容都包含在一个文件中，然后进行愚蠢的编译。 标准库在现代是一个笑话(默认情况下仍然没有线程或网络?) 大量令人讨厌的C语言(特别是所有在short/int/unsigned/等之间的转换)。

C#

泛型参数是不变的，c# 4.0为泛型类型引入了协方差和逆变性 可覆盖的类成员必须显式地标记为virtual

Java

缺少无符号数字数据类型 基本数据类型不是对象

Python 3

both tabs & spaces allowed for indentation And you'd think people learn from the past (Makefile). Just pick spaces and forbid tabs. YAML got it right. lack of popular third-party libraries The standard library is great, but a lot of what makes Python 2 so powerful lies in the third-party realm. Python 2 got this right :-). IEEE floats Floating points in programming languages are confusing because they're different from the way we use them in math. Instead, the number operations should be viewed as expressions that are only converted to a decimal point format when needed (i.e. printing to a screen). Maple and Mathematica did this right I think. the character set for identifiers is too restricted list.empty? is better than list.is_empty or even len(list) != 0. Similarly, process.kill! would be better than process.kill. Ruby and lisp got this right. when calling a function you must always write parentheses It would be nice if we could omit them in unambiguous cases. How is it again? dict.items or dict.items()? Ruby got this one right, too.

关于c#:

I hate that there is no keyword to specify which exceptions are thrown from a method like in java. Its a much better way to document exceptions than using an XML comment. I would also want a much better syntax for generic constraints like oring and anding of constraints. Why a method can't return more than one value? Lack of support for aspect oriented programming in the language. Why can't you annotate each one of the property accessors with an attribute? Lack of builtin regexp support like in perl.

c# 4.0

“动态”关键字，被滥用的时机已经成熟。如果你想要/需要使用反射，使用并让它明显地显示你正在使用它，不要试图用动态来伪装它。
