我对特尔斐的5分:

Procedures and functions aren't necessarily distinguished from variables if not parameterized (eg, I can have statement such as x := GetPositionOnScreen; instead of x := GetPositionOnScreen();) Try/Finally and Try/Except needs to be nested (stated once before, but it's still one of mine as well). Not case sensitive. Can have a multiple objects (functions, global variables, local variables) named the same and Delphi will happily try to figure out what you mean. names should be unique. Odd if condition rules. a single conditional check doesn't require a () around it, but if I do multiple checks, I need a () around each one, and sometimes multiple nested sets for bigger checks. No inherited includes. If I need to reference functionality from the Windows unit in a base and an inherited form, I have to include Windows in both.

C#

当被枚举的集合中的对象发生变化时，foreach命令弹出， UI控件吐出假人，因为它们在错误的线程上访问。当然是所有的调度员。调用可以移动到CLR管道， PInvoke，编组等， 我浪费了两年时间学习远程遥控， 它没有露比性感。

我的常用语言是爪哇语。这就是我讨厌它的地方:

5)。缺少指针 4)。异常捕捉 3)。布尔类型 2)。BigDecimal类型 1)。c#爱好者和Java爱好者

布尔值可以为空。我觉得这是违反直觉的。

BigDecimal是一个库，而不是一个语言特性。我对BigDecimal和Exception捕获的烦恼主要源于编写测试类，这些测试类必须跳过一堆箍才能完成实际工作。我应该澄清一下，我对这些事情很恼火，我不打算游说改变。

C++

太容易随机破坏内存并创建几乎不可能找到的错误(尽管Valgrind在修复这个问题上走了很长的路)。 模板错误消息。 在使用模板时，很容易将所有内容都包含在一个文件中，然后进行愚蠢的编译。 标准库在现代是一个笑话(默认情况下仍然没有线程或网络?) 大量令人讨厌的C语言(特别是所有在short/int/unsigned/等之间的转换)。

哇，我很惊讶SQL还没有出现在这里。我猜这意味着没有人喜欢它:)

跨实现的语法不一致 细微的代码差异可能会因为看似模糊的原因而产生巨大的性能影响 对文本操作的支持很差 入门成本低，但掌握这门语言的学习曲线陡峭 最大限度地标准化社区的最佳实践，这包括语法风格。

.．.还有一些额外的讨厌它的理由，不需要额外收费

the WHERE clause goes last, making it easy to prematurely execute an UPDATE or DELETE, destroying the whole table. Instead, the WHERE should go somewhere up front. It's difficult to implement relational division. I can set a value to NULL, but I can't test it for equality with NULL. I can check IS NULL, but that just complicates code -- needlessly so, in my opinion. Why do we need to completely respecify the formula for a GROUPed column, rather than setting an alias on the column and then GROUP BY the alias (or column index as with SORT)?

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:)
