最近Stack Overflow上有一群讨厌perl的人,所以我想我应该把我的“关于你最喜欢的语言你讨厌的五件事”的问题带到Stack Overflow上。拿你最喜欢的语言来说,告诉我你讨厌它的五件事。这些可能只是让你烦恼的事情,承认的设计缺陷,公认的性能问题,或任何其他类别。你只需要讨厌它,它必须是你最喜欢的语言。

不要拿它和其他语言比较,也不要谈论你已经讨厌的语言。不要用你最喜欢的语言谈论你喜欢的事情。我只是想听到你讨厌但能容忍的东西,这样你就可以使用所有其他的东西,我想听到你希望别人使用的语言。

每当有人试图把他们最喜欢的语言强加给我时,我就会问这个问题,有时是面试问题。如果有人找不出他最喜欢的工具的5个缺点,那他对它还不够了解,不能提倡它,也不能利用它赚大钱。他还没有在足够多的不同情况下使用它来充分探索它。他把它作为一种文化或宗教来倡导,这意味着如果我不选择他最喜欢的技术,我就错了。

我不在乎你用什么语言。不想使用特定的语言?那就不要。你通过尽职调查做出了明智的选择,但仍然没有使用它?好吧。有时正确的答案是“你有一个强大的编程团队,有良好的实践和丰富的Bar经验。改成Foo是愚蠢的。”


This is a good question for code reviews too. People who really know a codebase will have all sorts of suggestions for it, and those who don't know it so well have non-specific complaints. I ask things like "If you could start over on this project, what would you do differently?" In this fantasy land, users and programmers get to complain about anything and everything they don't like. "I want a better interface", "I want to separate the model from the view", "I'd use this module instead of this other one", "I'd rename this set of methods", or whatever they really don't like about the current situation. That's how I get a handle on how much a particular developer knows about the codebase. It's also a clue about how much of the programmer's ego is tied up in what he's telling me.

憎恨并不是衡量人们了解多少的唯一尺度,但我发现它是一个相当不错的尺度。他们讨厌的事情也让我知道他们对这个话题的思考有多好。

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

VB6

仅Windows。 不再支持。 数组可以从任何数字开始,而不是全部归一化为0。 已编译的应用程序依赖于许多dll才能正常运行。 许多复杂的控件(如浏览器控件或复杂的代码段)在运行未编译的代码时往往会破坏IDE,但在编译后却可以正常工作。

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.

JavaScript

Function object syntax: f = new Function( "foo", "bar", "return foo+bar;" ); (It takes n arguments, the first n-1 are arguments for the function, then nth is the actual function, in string form. Which is just silly.) Function arguments can be repeated. f = new Function( "foo", "foo", "return foo;" ); The last repetition is the only one ever used, though: f( "bye", "hi" ) // returns "hi" f( "hi" ) // returns undefined E4X should just die. My users are always complaining that it doesn't work the way they think it will. Let's face it, when you need a page and a half of psuedocode for a setter, it's time to rethink things. A standard notion of stdin/stdout/stderr (and files!) would be nice. null != undefined It's irritating to have to handle them both. Sometimes it's useful, but most languages manage to limp along fine with one.

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
