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。

VBA(因为你认为你的语言不好)

Whitespace inside a line is rigidly enforced. Statements just end, and require a " _" to break to the next line, but not every line can be broken. No ++,--,+=,-= statements. Seriously? Arrays can begin at any index, not just 0. Some types (i.e.: fixed-point "Decimal" value) must be subtypes of Variant, and aren't available as their own type. != and <>. "=" is used as both comparator and assigning, instead of splitting into "=" and "==". "Option Explicit". UI hasn't been updated since 2000. Office2k7 didn't upgrade to VB.NET Most object models are non-sensical and overly verbose.

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)。

我的常用语言是爪哇语。这就是我讨厌它的地方:

5)。缺少指针 4)。异常捕捉 3)。布尔类型 2)。BigDecimal类型 1)。c#爱好者和Java爱好者

布尔值可以为空。我觉得这是违反直觉的。

BigDecimal是一个库，而不是一个语言特性。我对BigDecimal和Exception捕获的烦恼主要源于编写测试类，这些测试类必须跳过一堆箍才能完成实际工作。我应该澄清一下，我对这些事情很恼火，我不打算游说改变。

我使用Java，我最大的不满是字符串操作的低效率。当你使用+运算符时。说真的，难道编译器不能计算出我添加了多少字符串，然后在后台为我生成StringBuffer的东西吗?

通常，使用+的代码比StringBuffers操作序列更具可读性。

另外，我讨厌本机数组和集合框架之间的冗余。. toarray()的语法极其丑陋。

Haskell

Sometimes the type system feels backwards. What if I don't want the compiler to infer types for my variables? What if I want the opposite, where it does constraint checking on said variables? For example, instead of inferring the type of the elements of a list, it instead makes sure that they all belong to a particular typeclass. This is a subtle but huge difference that makes it difficult for me to program UIs. It can be done, but it takes more effort than it does in some other languages. Haskell rocks for the non-UI parts, but the UI I leave to an untyped language. Allowing the construction of infinite values leads to some really frustrating errors sometimes. NoMonomorphismRestriction. Bytestring handling bites me in the ass sometimes and you don't know it until your program crashes because you mixed them up improperly. Something is wrong here, when we are losing type information that should have prevented this. Typeclasses should be automatically derived for trivial cases, like witness types, but there's a strong potential for abuse there.
