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。


当前回答

Common Lisp:

关键词往往太啰嗦。 库支持是可怜的。 在希望更严格地处理内存的操作系统中不能很好地工作。 没有与操作系统交互的良好工具。 “循环”功能没有很好地定义,当然看起来也不像Lispy。

其他回答

C#

我知道这很愚蠢,但我希望数据类型转换为我自己想要的,而不是我必须添加(int)或转换。ToInt32或者别的什么。这样可以节省我的时间。让我烦恼的是,如果我写了一些东西来输出一个int型,结果我需要一个long型,然后我经常不得不从头到尾修改我所做的一切来让它工作。就为了我!

抱歉,我想不出5个,但我是新手,所以也许我以后会回来添加更多:P

闲聊

我不想再用java、delphi、c#或ruby进行开发(这是不切实际的,因为我公司的主要开发语言是c#、delphi和java)。 从左到右的评估。 有类注释但没有方法注释(至少在Squeak中) 没有真正的标准库,在细节上有很多差异 缺少名称空间

Common Lisp

conditions aren't classes (since classes came later), even though their interface is almost identical some of the names are just weird, e.g., flet / labels (only difference: scope), and defvar / defparameter (only difference: behavior when already defined), or any of the bit-twiddling functions (dpb, ldb, etc.) packages are ... really hard to get right -- every time I think I understand them, they don't do what I want built-in data structures and functions aren't as generic as they could be (e.g., why can't I define my own hash function portably?) multiple namespaces for functions, variables, etc. (I'm not opposed to this in principle, but CL made it too complex; Norvig has said he can't tell from the spec but there appear to be at least 7 namespaces)

c#:

1)静态方法必须是类的成员

2)静态扩展方法只能添加到静态类中

3)接口函数的实现不会被标记为“override”之类的东西来显示它们来自基类或接口(这使得你很难确保你正在重写你所期望的方法(具有正确的签名))。

我只有3个。我想那很好。

C

bit fields -- they aren't well specified by the language and how they work is compiler dependent and architecture dependent. It's often hard to find where a particular symbol is defined in a large mass of code, esp. if that symbol is produced by a macro. Which reminds me... The preprocessor is a rather ugly hack, amenable to all sorts of abuse. lack of standard sized integers (remedied by uint*_t lately, but there is lots and lots of old code floating around out there with custom typedefs or #defines for DWORD, WORD, BYTE, etc.) Lack of something akin to Perl's cpan.org (would love to be wrong about that one.)

编辑: 在考虑C的CPAN时,我想……我该怎么称呼这样的东西,然后想到了“ccan”,然后谷歌了一下,我看到了这个: http://ccan.ozlabs.org/

不过,它似乎还处于起步阶段。
