经过一些思考后重写了这篇文章…

虽然我喜欢PHP，但我讨厌它的五个方面(排名不分先后):

内置函数中的命名和参数顺序不一致。 面向对象的数组方法多亏了SPL，但遗憾的是还没有字符串。 PHP本身没有真正的并发，只有通过托管web服务器的多处理 没有像JavaScript那样的异步调用 只能通过扩展进行操作码缓存。不是很糟糕，只是有点烦人。

这些是令我烦恼的语言特性(或缺乏)，但更大的问题是这些与人/社区相关的东西:

事实上，很多使用PHP的人，对编程和良好实践一无所知，从而产生了非常混乱的代码。JavaScript也有同样的问题。 大量的教程/书籍传授了非常糟糕的做法和风格。这可能是第三条的主要原因。 它的坏名声主要是因为第三条和第四条。

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! ;-)

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

c#(好吧，我猜一部分是VisualStudio IDE):

No covariance (yet), like Class<D> cannot be used in place of Class<B> even though type D derives from type B. Graphic designers don't support generic based inheritance (or inheritance from abstract classes), even though the inheritance itself works just fine if you work around the designer problems by adding extra inheritance levels just so designers always see concrete non-generic variants of your code. No constructor inheritance No constructors in where clauses of generic type parameters VisualStudio seems to have a tendency to mysteriously check out files (like project files and/or unit test definitions) when opening a solution, even though the files do not seem to actually get altered.

如果你明天再问我，可能会有不同的名单。即使协方差和设计师的麻烦将在我的前5名，直到他们被解决(随着方差添加到c# 4.0，这似乎已经发生了至少一个…)

c# / .net:

Classes should be sealed by default There should be no lock statement - instead, you should have specific locking objects, and there should be methods such as Acquire which return disposable lock tokens. Corollary: there shouldn't be a monitor for every object. GetHashCode() and Equals() shouldn't be in System.Object - not everything's suitable for hashing. Instead, have an IdentityComparer which does the same thing, and keep the IComparer<T>, IComparable<T>, IEqualityComparer<T> and IEquatable<T> interfaces for custom comparisons. Poor support for immutability Poor way of discovering extension methods - it should be a much more conscious decision than just the fact that I'm using a namespace.

这些都是我想出来的，明天问我，我会想出一个不同的5个:)

我讨厌Java的五个方面:

没有一级函数。 没有类型推断。 缺乏理智的默认值在eg图形。 NullPointerException不包含更多关于什么是null的信息。 毫无意义的“可配置”框架/服务提供者接口/工厂类/依赖注入系统的激增。可配置性几乎从未使用过，严重违反了DRY，代码的大小增加了四倍，易读性减少了一半。

我知道，我应该试试Scala。
