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。

Lua

我喜欢这门语言,但是有一些事情困扰了我很多年!

No (built-in) support of binary operations (as of 5.1, it might come with 5.2). Should have a built-in binary buffer implementation, allowing for example in place long string concatenation. I know it doesn't fit well in the syntax, but sometime I miss longVariableName++ or verboseVariableName += 5. Reference assumes knowledge of C (I have it but it is a minus for newcomers) and defers some help to C reference! And sometime it is too terse. It is starting to have a good deal of libraries, but you have to get them from various places. On the other hand, the download is very small! ;-)

其他回答

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++缺乏好的重构工具,缺乏受控异常

Java缺少模板,缺少const关键字

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
}
?>

The behavior AndAlso / OrElse and And / Or seems backwards. Perhaps they should be switched. When can only be used for exception catching. The ability to do a When conditional would be nice for some other things. There is no friggin Refactoring in the VS IDE (not really the language's fault) like there is with C# Not <obj> Is Nothing. Yes, this has been remedied by IsNot, but for some reason I see the Not Is being used too often. (I see it much more frequently with devs who speak english as a second language, does it make better sense from that angle?) It doesn't require the () on ToString() and most functions. (Leads to sloppy coding habits) Having to do _ when breaking a line. It allows optional parameters. (Leads to sloppy coding habits) declaring an array is done by UpperBound and not by capacity. "Dim arr(2) as String" will actually hold 3 elements. Having = be a comparison and assignment operator.
