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。

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.

Python:

处理数字太慢了。这不是什么大问题,除非…… 不能简单地在程序中包含导入时自动编译的C代码。 在py3k接管之前,我们仍然要忍受愚蠢的整数除法规则。 在py3k接管之前,像imap和izip这样的好东西仍然存在于一个单独的模块中。 在py3k接管之前,我们还有很多工作要做。

没有Django for Python 3。 静态类型。是的,动态类型是很棒的东西,但有时我确实想让它成为静态的。 正确的unicode支持(在Python 3中修复) Construtors命名。我讨厌代码中的所有这些下划线。 线程的效率不是很高

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.

我自己最讨厌c++的5个地方:

自动生成构造函数、析构函数和赋值操作符。伙计,每当我在课上没有声明什么东西时,这意味着我不需要它,而不是我忘记了。你们这些编辑们,听到了吗?!

[4]模板语法。哦,我真的需要输入所有这些“<”和“>”,每当我决定从类主体提取定义?

[3]字符串。天啊,我受够了“const char*”,我必须处理NULL情况,我必须浪费O(N)来获得它的长度,我必须为concat操作分配缓冲区。

[2] Macroprocessing。每当我不明白,什么是我的编译器,我开始寻找宏。

[1]操作符重载。我看到代码“A + B * C”,在我看到A、B和C的实际类型之前,我说不出这个代码是关于什么的。

Python

Standard library disobeys their own style guidelines in many places. (PEP-8) Py3k's super keyword is full of unwanted magic (you can't assign it to a different name, works without self, why do we have this explicit parameter at all?) Unicode support is incomplete in Py2k and sucks in Py3k (standard input in unicode, no binary data! WTF? Creating a new WSGI standard is hacky.) The GIL. Very limited multi-threading support (with CPython) PyPI (Python Package Index) sucks. Envious glance at rubygems
