你的亮点是图灵完备?!我可以在Perl正则表达式中做更多的事情! 缺少对象。来吧,人!就像，你好… 没有网络库。我只想刮一个网页，天哪。 没有一级函数。恭喜你——你可以同情你的Java朋友了。 一个无限的磁带存储，没有其他。这是如此的矫情，我们可能还在写Lisp。

到目前为止，我最讨厌我最喜欢的语言的地方是我的选择总是在变。每次我以为我找到了命中注定的那个人，我就会发现我讨厌他的5个(或更多)地方。然后那边的草看起来更绿……

那"我讨厌某些语言的五件事"清单呢?: D

把橙色涂成红色并不能让它成为苹果。

当设计一种语言时，设计者通常会考虑它的用途。用它做一些完全不同的事情是可以的，但是当它不起作用时抱怨是愚蠢的。Python。我相信总有一天会有人用Python代码创建exe工具。你到底为什么要这么做?不要误解我的意思，这样做很好，但没有任何用处。所以别再抱怨了!

一个设计良好的项目很可能包含来自多种语言的代码。这并不是说你不能只用一种语言完成一个项目。有些项目可能完全在您所使用的任何语言的能力范围内。

4-你是用木腿站着吗?

The platform can be a large influence of what the language can do. With nowadays garbage collectors, or well even pascals early attempt at "garbage collection", can aid in memory fade (maybe malloc more ram??). Computers are faster and so of course, we expect more out of our languages. And quite frankly, we probably should. However, there is a huge price to pay for the convenience of the compiler to create hash tables or strings or a variety of other concepts. These things may not be inherit to the platform of which they are used. To say they are easy to include to a language just tells me you may not have a leg to stand on.

3-到底是谁的错?

Bugs. You know. I love bugs. Why do I love bugs. Because it means I get to keep my job. Without bugs, there would be many closed pizza shops. However, users hate bugs. But here is a little splash of cold water. Every bug is the programmers fault. Not the language's. A language with such a strict syntax that would significantly reduce how many bugs were possible to generated would be a completely useless language. It's abilities could probably be counted on one hand. You want flexibility or power? You've got bugs. Why? Because you're not perfect, and you make mistakes. Take a really identifiable example in C:

int a[10];
for (int idx = 0; idx < 15; idx++) a[idx] = 10;

我们都知道会发生什么。然而，也许我们中的一些人没有意识到…这种功能是非常有益的。这取决于你在做什么。缓冲区溢出是该功能的代价。上面的代码。如果我真的把它公之于众。这是再一次. .和我一起说。“我的错”。不是C，因为你允许我这么做。

2-我们不应该把它放进回收站吗?

It's very easy to point at a feature in a language we don't understand because we don't use it often and call it stupid. Complain that it's there etc. Goto's always entertain me. People always complain about goto's being in a language. Yet I bet your last program included a type of goto. If you have ever used a break or a continue, you've used a goto. That's what it is. Granted, it's a "safe" goto, but it is what it is. Goto's have their uses. Whether "implicit" gotos like continue or break are used or explicit gotos (using the actual keyword "goto" for whatever language). Not that language developers are flawless, but typically... if functionality has existed since the dawn of time (for that language). Likely that aspect is a defining quality of that language. Meaning.. it's being used and likely is not hanging around because of backwards compatibility. It's being used today. As in 5 minutes ago. And used properly. Well.. arguably someone is using it improperly as well, but that relates to #3 on my list.

1. -一切都是客体。

Ok.. this one is really a subset of #2. But this is by far the most annoying complaint I see in hate lists. Not everything is an object. There are a great many of concepts that do not belong or need to be objects. Putting things where they don't belong is just ugly and can decrease efficiency of a program. Sure. Maybe not much depending on the language. This also relates to #5. This means... yes. Global are ok. Functions as apposed to static methods are ok. Combining OO programming with global functions is ok. Now.. that doesn't mean we should all go out and "free" our code from it's object models either. When designing a section of code or a whole project, what happens behind the scenes should be considered when putting it together. Not only where that concept lives and many other factors. Why wrap global functions within classes or name space concepts if it serves no purpose? Take static member variables. That greatly amuses me because.. well..Depending on the language and implementation of course, but generally speaking, you just declared a global. Yes, there are some reasons to wrap these non-OO concepts in OO wrappers. One of course being self documenting code. That can make sense. So.. like I say. Don't go out and "free" your code. But any good modern language will have a global concept outside of it's OO modeling. Yes I'm specifically meaning to point out that an OO programming language without a global concept most likely has a serious design flaw. Again though.. depends on the intention and design of the language so I'm not attempting to pick on any specific language and there are far too many to analyze right here. Anywho, Consider where the code should live and be the most effective. Adding a bunch of flare to something which doesn't add functionality or support just wears down the keyboard faster. It doesn't do anybody any good. Well.. unless you like brownie points from the person who probably incorrectly taught you that everything is an object.

In short, programming isn't just mindlessly tapping on the keyboard. There are a lot of design considerations to any project. I know it's cliche, but you have to look at it from every angle. Even with nowadays type-safe languages. You don't just chuck code out and expect it to work well. Sure.. it may work, but it may not be the right way to go about it. Overall, pick the language and format that is best suited for the specific job AND the environment. But no language takes away the thought behind it. If you're not thinking.. you're just typing.

标准库的奇怪之处:它并不总是显示最佳实践，而且文档不足 硬编码FunctionX, TupleX类 缺乏属性:getter和setter是分开的，这违反了DRY，并且使得像FRP这样的事情几乎不可能实现 需要= _来初始化属性

Python,:

No switch keyword. And NO, dictionary is not a replacement for it. Not even a bunch of elif statements. Inconsistent line break handling. Why can I do: test = (1, 2, 3) And not: from itertools import cycle, islice, izip Why can't I do: if stuff \ and foo \ or bar: return "Formated string with %(arg)s" % \ {'arg': "bloody slash"} without using slashes? There is not one obvious and only one way to do it. Python fails on its motto just like Java failed on "Write once run anywhere". # what somebody from an another language would do if not test.has_key('foo'): test['foo'] = 0 n = test['foo'] = test['foo'] + 1 vs # what an agnostic beginer would do try: test['foo'] += 1 except KeyError: test['foo'] = 1 n = test['foo'] vs # what you end up after looking for dictionary default value in the python doc test.setdefault('foo', 0) n = test['foo'] = test['foo'] + 1 vs # what I would do n = test['foo'] = test.get('foo', 0) + 1 And the worst is that they don't do exactly the same thing. There are subtle differences. Choice between spaces and tabs. There should be no choice. Pick on, set it in stone and stop fighting. Why can you do that: test = {} test['foo'] = 0 but not: test = [] test[] = 0

附注:" ".join(l)是优秀的人。不要抱怨它，这并不明显，但考虑到迭代器模式，这是正确的方法。

Python:

1) It's a scripting language and not a fully compiled one (I'd prefer to be able to compile binaries—I don't care about bytecode). This is very annoying if I have to use very many libraries (i.e. everyone who uses my program has to install all the libraries, and this basically means no normal people will be able to, or have the patience to, properly set it up—unless I do a ton of work that should be unnecessary). I know ways to make binaries, but they don't always work, and I'm guessing they bundle the interpreter in the binaries anyhow (and I don't want that). Now, if I could get a bytecode compiler that would include copies of all the files that I imported (and only those) to be placed in my program's folder, that might be a suitable compromise (then no one would have to download extra libraries and such). It would also be nice if the compiled python files could be compressed into a single file with one specified as the file to run the program before this is done.

2)有时看起来有点bug;有几次，应该工作的代码根本没有工作(没有程序员错误)，特别是与“from moduleX import *”和其他导入相关的问题有关的代码，以及一些与全局和局部变量有关的问题。

3)最大递归深度可以更高。至少有一次，我觉得我需要它去更高的地方。

4)没有switch语句(更不用说允许数字、字符串和范围的语句)

5)新版本的Python似乎取消了很多有用的字符串操作，而且似乎没有简单的文档说明如何在没有它们的情况下做同样的事情。

6)强制自动垃圾收集(我希望能够手动执行，尽管不一定强制执行)。

7)没有预先制作的定时器类没有使用GUI(好吧，可能有一个，但在我所做的所有搜索之后，它肯定不方便找到!我确实找到了一些东西，但当我尝试时，它根本不起作用。)所谓计时器，我指的是每隔x秒执行一个指定函数的排序，并能在需要时关闭它，等等。

8)社区里举例的人很少告诉我们他们导入了哪些模块，以及他们是如何导入的。

9)与Lua集成的支持并不多。

10)似乎没有办法向一个类的特定实例(而不是整个类)添加一个额外的函数，除非你动态地向该类添加一个对象变量，该对象具有所需的函数(但仍然，你必须为此创建另一个类)。
