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。

我是在冒险,因为我不能全职使用它,但无论如何我会尝试一下!

Perl 6

func("frew") != func ("frew") It annoys me, but there is good reason for it. In Perl 5 print (5 + 6) * 10 still gets me every now and then It may be easier to parse than Perl 5 in a lot of places, but it still kills my editor sometimes It still has a lot of the line noise Perl 5 which scares a lot of people. That means it's harder to get them excited etc. There are no libraries yet. This will be a non issue if Perl 6 does indeed end up supporting Perl 5, but that may be a burden not worth bearing. There's no REPL, or what rubyists would call irb. A solid interactive Perl 6 with tab completion, color coding, etc, would make using and learning it so much nicer. Currently the documentation is basically the English spec. Not exactly an easy read. I know it's a stupid cliche, but it's not out yet! (I am allowed to complain because I am helping :-P)

前三点是语言;剩下的并不是语言本身,而是它还没有问世的事实。

Common Lisp

缺少提供更现代功能的标准库(套接字,线程,…) 是否可以使用映射到本机窗口系统的标准化UI Scheme将lambda表达式赋值给变量并将变量直接作为函数调用使用的能力看起来比APPLY for FUNCALL更整洁。我猜这是使用多个名称空间的副作用 标准化的库源代码级打包系统,以便可以从多个实现中轻松使用它们

我想知道强类型的口齿不清会是什么样子

再给c++投一票…仍然是我最喜欢的语言,有几个亲密的追随者——C和Python。以下是我目前最讨厌的名单,排名不分先后:

Plethora of integer types inherited from C - way too many problems caused by signed vs. unsigned mistakes Copy constructors and assignment operators - why can't the compiler create one from the other automatically? Variable argument madness - va_list just doesn't work with objects and I'm so sick of problems created with sprintf(), snprintf(), vsnprintf(), and all of their relatives. Template implementation is required to be fully visible at compile time - I'm thinking of the lack of "export" implementations or at least usable ones Lack of support for properties - I want to have a read-only member like "a.x" that can be read publicly and only assigned internally. I really hate the "val=obj.getX()" and "obj.setX(val)". I really want properties with access control and a consistent syntax.

ColdFusion

大型Flash表单的编译时间。 动态变量类型(有时我讨厌它们) CFScript缺乏特性。 CFTable(永远不能正确显示)。 CFChart中缺少图表类型。 完全缺乏NTLM支持(企业就绪-是的) cfc中的低能变量作用域 没有一个真正的NULL的概念-你的变量只是消失! 没有办法测试某些东西的存在(比如作用域,只是它们内部的成员)

Objective Caml

缺少名称空间。 啰嗦类和对象注释。 复杂的构建系统。 不方便制作中缀。

Lua

我喜欢用Lua编程,但下面是让我头疼的事情:

没有办法用这种语言编写API——不像C .h文件或Java接口 语言有一流的功能,但有人忘记告诉设计库的人。 编写函数的语法太重量级了。 语法分为语句和表达式。 表达式形式是贫乏的:没有let形式,没有真正的条件表达式,……

尽管如此,我还是坚持认为Lua非常棒:-)
