哇，我很惊讶SQL还没有出现在这里。我猜这意味着没有人喜欢它:)

跨实现的语法不一致 细微的代码差异可能会因为看似模糊的原因而产生巨大的性能影响 对文本操作的支持很差 入门成本低，但掌握这门语言的学习曲线陡峭 最大限度地标准化社区的最佳实践，这包括语法风格。

.．.还有一些额外的讨厌它的理由，不需要额外收费

the WHERE clause goes last, making it easy to prematurely execute an UPDATE or DELETE, destroying the whole table. Instead, the WHERE should go somewhere up front. It's difficult to implement relational division. I can set a value to NULL, but I can't test it for equality with NULL. I can check IS NULL, but that just complicates code -- needlessly so, in my opinion. Why do we need to completely respecify the formula for a GROUPed column, rather than setting an alias on the column and then GROUP BY the alias (or column index as with SORT)?

Python:

1) line continuation syntax: "...\" works, but "...\ " does not, and that trailing space is generally invisible, without unusual eol-marking by editer. 2) a bare 'raise' is invisible in the stack trace, as the stack trace looks like the previous raised exception. 3) slow 4) poor integration into web-servers (mod_python: dead, mod_wsgi: limited scope of operation). This is complicated by 3], requiring daemonization or some sort of memory-persistance to perform well. 5) overly tolerant of mixed tabs and spaces, allowing changes to control flow to sometimes remain hidden. (maybe fixed in recent versions)

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.

ActionScript / AS3

没有抽象类 没有私有构造函数(所以单例是一种hack) FP10之前没有类型化数组 Flash IDE中的编译/发布时间慢得离谱 内置函数(例如Math)的性能较慢

除此之外，它实际上是一种很好的语言——与流行的观点相反，它比JavaScript好得多，比PHP之类的语言好一百万倍。

C

No parametric polymorphism (i.e. C++ templates). It makes writing reusable data structures and algorithms a pain (and there's hardly any static checking). See for instance the comparator argument to qsort and bsearch: the comparator takes void pointers :( No library of data structures. I really hate writing my own hash table. I also really hate scouring the web for a library of reusable data structures. Especially if it turns out to be incomplete. Strings. Inefficient representation, unwieldy if you make it sane, too hard to safely input a string. No standard for snprintf. Too hard to create a format string with sprintf, then use that to create a string with sprintf again, in a safe way. Only lexical macros. If different compilers expects function annotation in different places, I have to put the same HAS_NO_SIDE_EFFECTS in different places. Why can't I just grab the function, switch over the compiler type, and then insert it at the right place by a macro call? No portable libraries for common functionality. For sockets and threading, I use SDL---a frigging game library. For .ini-style parsers, the only library I could find which was packaged for ubuntu, I posted on the daily wtf (it calculates an array of hash values, then does a linear scan through it...)

C++

Template syntax is heavy and unweildy. Let's see, for(map<string, int>::const_iterator it = mymap.begin(); it != mymap.end(); ++it). Design errors in the STL. Should changing allocation strategy for your vector really change its type? Overly complex type system. Type T1 has a convert-to-T2 method, and T2 has an implicit from-T1 constructor. Which is called? How does overloading, overriding and multiple inheritance interact? Poorly, I guess... Incredibly long and unwieldy error messages from templates. You know what I mean... References means you can't see output parameters at call sites. In C, you can guess what foo(bar, &baz) can and can't modify.
