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

Javascript;

the dynamic binding of "this" is very confusing and dangerous if you don't know exactly what you're doing. a function declaration requires the keyword "function". It's not the typing I object to, it's the reading it when I want to do something slightly clever. Hrm now I think of it maybe that's a plus. Discourages me from doing clever things. As a result of number 2, it's often less code (in terms of characters) to just copy/paste a code segment than to declare it as a function, if it's a fairly short idiom. This unfortunately promotes bad practice, especially in my own code. Javascript makes motions at being a functional language by having first class functions and closures, but there's no way to verify referential transparency in a function, at either runtime or compile time. Without this, some architectures become either risky or bulky. Its fantastically bad reputation, and thus my inability to say "I program in javascript" to anyone without being laughed at.

Python:

我仍然是python的一般用户，所以我的抱怨可能只是知识的锁或误用。欢迎提出意见。我很喜欢这门语言。

Poor thread support and GIL. If you'd like to take use of multicore platform, most of the python programmers would probably recommend multiprocessing or some sort, don't use threading. It wouldn't give you the performance you are expecting. property only for instance variable. _class_var = property(classmethod(some_method)) just wouldn't work. How can I get a property wrapped class variable? no access control. All access controls are syntax mangling. Like private is __private, protect is _protected, etc... And hope that everyone programs python follows the naming convention. Come on, we can do better than that. I agree the python philosophy of being simple and clear syntax but some simple and clear syntax not being supported seems lock of good judgement, in my opinion. Such as, a++, ++a, a-- and --a, self-de/increment, what's wrong with those? foo = (a > b ? a : b) unary operation, what's wrong with those? (I know py2.6 has something similar introduced, but given the massive support of almost every other language for those simple syntax, why reinventing the wheel? why not just follow the best practice? Shouldn't a good thing just keep in its good "form"?) Program to interface. Python has no interface or abstract class concept (py3k has something called abc), everything is concrete. Providing an "interface" or "abstract" keyword to build class skeleton and guard class inheritance and extension wouldn't be a bad idea I think. It helps on top-down design. Currently, I just have to fill the each of methods with NotImplementedError, quite a tedious job. I have to add this. version less than 3.x has str and unicode types. This is a true nightmare. It makes ascii and non-ascii/unicode mixing most likely to fail (bad, bad)

我看到人们抱怨速度。我不明白。它是一种解释语言，代码直到运行时才编译成机器代码，这就是它的本质。你不能比较解释语言和编译语言的速度。据我所知，在解释/脚本语言中，python并不慢。

我是在冒险，因为我不能全职使用它，但无论如何我会尝试一下!

Perl 6

func("frew") != func ("frew") It annoys me, but there is good reason for it. In Perl 5 print (5 + 6) * 10 still gets me every now and then It may be easier to parse than Perl 5 in a lot of places, but it still kills my editor sometimes It still has a lot of the line noise Perl 5 which scares a lot of people. That means it's harder to get them excited etc. There are no libraries yet. This will be a non issue if Perl 6 does indeed end up supporting Perl 5, but that may be a burden not worth bearing. There's no REPL, or what rubyists would call irb. A solid interactive Perl 6 with tab completion, color coding, etc, would make using and learning it so much nicer. Currently the documentation is basically the English spec. Not exactly an easy read. I know it's a stupid cliche, but it's not out yet! (I am allowed to complain because I am helping :-P)

前三点是语言;剩下的并不是语言本身，而是它还没有问世的事实。

c#中缺少预处理器。

我知道他们把它放在一边是因为有些人会滥用它，但我认为他们把孩子和洗澡水一起倒掉了。代码生成被认为是一件好事，在c++中，预处理程序是我的第一个代码生成器。

C#

当被枚举的集合中的对象发生变化时，foreach命令弹出， UI控件吐出假人，因为它们在错误的线程上访问。当然是所有的调度员。调用可以移动到CLR管道， PInvoke，编组等， 我浪费了两年时间学习远程遥控， 它没有露比性感。
