C(好吧，这不是我最喜欢的，但当时还没人做过。)

套接字库语法。 没有函数重载。 c风格的字符串。 缓冲区溢出。 神秘的语法。我不知道有多少次我查到像atoi这样的东西，拍着我的额头，然后大喊“当然!”

编辑:如果我使用更多的库代码(就像我用套接字做的那样，但那些特别糟糕)，我可能会想出更多的库代码，但我已经觉得我选择C语言是在作弊。许多语言的存在只是为了取C语言的好的部分，取代坏的部分，这有点像在徒劳无益。

PHP

没有构造函数重载 不一致的函数命名(str_replace，但strtolower) define()不像c++那样逐字替换全局变量。 在与XHTML组合时，像if-语句这样的语句必须以不缩进开始，即使为了保持XHTML缩进一致，XHTML是缩进的。

Ex:

你必须输入:

<?php
if($x == NULL)
{
?>
                     <p><?= $x . ' is null' ?></p>
<?php
}
?>

错误捕获非常糟糕

(不知道为什么又把5号改成了1号，随便了)

Lua

我喜欢用Lua编程，但下面是让我头疼的事情:

没有办法用这种语言编写API——不像C .h文件或Java接口 语言有一流的功能，但有人忘记告诉设计库的人。 编写函数的语法太重量级了。 语法分为语句和表达式。 表达式形式是贫乏的:没有let形式，没有真正的条件表达式，……

尽管如此，我还是坚持认为Lua非常棒:-)

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:

Lack of distinction between function pointers (executable) and data pointers (you really don't want to execute this). Extreme unreadability. Making code look like it does what it does is orders of magnitude more difficult than making it do the task in the first place. Lack of clear support for lisp-think. Doing functional things is possible, barely, but it's not clear. Serious inconsistency between libraries about how error codes are returned. Antiquated string handling. The strings aren't strings, they're null-terminated blobs. This is all manner of wince-worthy.

Lisp:

()需要按shift键。每次我口齿不清的时候，我就把它和[]交换。

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
