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。

HyperTalk:

很久很久以前就死了 没有简单的赋值(你不能说a:= 3,你必须说把3放进a 没有嵌套函数 没有真正的数据结构,只有字符串。要创建“列表”,您可以使用itemDelimiter分隔项并手动转义它们。你也可以得到行和单词比如txt的第5行第2个单词

说句题外话,我认为HyperTalk最酷的独特功能之一是特殊的it变量:

ask "How many years old are you?"
answer "You are " & it*12 & " months old."

Python

1-3:没有一个明显的打包/构建/文档系统的选择(比如Perl的cpan、POD或Ruby的gem、rake、rdoc)。 4: Python 3.0是不兼容的,需要两个源分支(2。x和3.x)用于每个Python项目。但是Python 3.0的不兼容性还不足以证明它的合理性。大多数py3k的优势都太微妙了。 5: Jython, IronPython, CPython不兼容。

PHP:

荒谬的assert()函数…它对里面的代码运行eval() ?>标签删除了它后面的换行符?! 奇怪的数字字符串处理(尝试将它们作为数组键) 令人痛苦的unicode支持似乎将不再被PHP 6解决 入门成本低意味着95%的人给PHP程序员起了一个可怕的名字——试图在这5%中找到一个人来雇佣是疯狂的。

帕斯卡对象:

There's a lot of jumping back and forth in the file you're editing since the interface and implementation are split into two parts but still jammed into the same file. Dynamic indexing of arrays, strings start at 1, you specify the starting index when declaring fixed arrays and dynamically allocated arrays always start at 0. Classes and objects (not to speak of interfaces) are bolted on top of the language and among other things can't be stack allocated like records can. When calling functions without parameters the () are optional, leading to a lot of pain when you are dealing with function pointers or trying to refer to the result of a function using the function name. Parameter lists can't handle fixed array types or function pointer types without external type definitions.

这仅仅是一种语言,一个标准库的遗憾借口,而脆弱的IDE应该有自己的列表。

我讨厌所有语言的五件事(至少就我所知):

Does what I say/type, not what I mean Will undoubtedly meet people who think they are experts in the language, but just make a mess of it (e.g. people who insist that removing comments/unused local variables will speed up execution time for a program) Unless the language is obsolete, then it will probably continue to evolve (either the actual language, or the concepts behind using it effectively) requiring you to actively develop with it so as to not fall behind. Can't modify the lexer/compiler (add in own context sensitive grammar) No perfect language (every language is missing some sort of useful feature that usually is either impossible to simulate, will unavoidable have an ugly interface or just require far too much time to implement and get it right)

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。
