这绝对是主观的，但我想尽量避免它变成争论。我认为如果人们恰当地对待它，这将是一个有趣的问题。
这个问题的想法来自于我对“你最讨厌的语言的哪五件事?”问题的回答。我认为c#中的类在默认情况下应该是密封的——我不会把我的理由放在这个问题上，但我可能会写一个更完整的解释来回答这个问题。我对评论中的讨论热度感到惊讶(目前有25条评论)。
那么，你有什么有争议的观点?我宁愿避免那些基于相对较少的基础而导致相当宗教的事情(例如，大括号放置)，但例如可能包括“单元测试实际上并没有多大帮助”或“公共字段确实是可以的”之类的事情。重要的是(至少对我来说)你的观点背后是有理由的。
请提出你的观点和理由——我鼓励人们投票给那些有充分论证和有趣的观点，不管你是否恰好同意这些观点。

编程是如此简单，一个五岁的孩子都能做到。
编程本身并不难，这是常识。你只是在告诉计算机该做什么。你不是天才，别自以为是了。

小代码总是更好，但是复杂?:而不是if-else让我意识到有时大代码更可读。
Having a process that involves code being approved before it is merged onto the main line is a terrible idea. It breeds insecurity and laziness in developers, who, if they knew they could be screwing up dozens of people would be very careful about the changes they make, get lulled into a sense of not having to think about all the possible clients of the code they may be affecting. The person going over the code is less likely to have thought about it as much as the person writing it, so it can actually lead to poorer quality code being checked in... though, yes, it will probably follow all the style guidelines and be well commented :)
大多数语言的支持者制造了很多噪音。
世界需要更多的goto
人们虔诚地避免goto，除了“我的教授告诉我goto不好”之外，没有其他理由。它们有一个目的，可以在很多地方极大地简化生产代码。
也就是说，在你所编写的99%的代码中，它们都是不必要的。
默认情况下，所有变量/属性都应该是只读/final。
这个推理有点类似于Jon提出的类的封闭论证。程序中的一个实体应该有一个任务，而且只有一个任务。特别是，对于大多数变量和属性来说，改变值是绝对没有意义的。基本上有两个例外。
Loop variables. But then, I argue that the variable actually doesn't change value at all. Rather, it goes out of scope at the end of the loop and is re-instantiated in the next turn. Therefore, immutability would work nicely with loop variables and everyone who tries to change a loop variable's value by hand should go straight to hell. Accumulators. For example, imagine the case of summing over the values in an array, or even a list/string that accumulates some information about something else. Today, there are better means to accomplish the same goal. Functional languages have higher-order functions, Python has list comprehension and .NET has LINQ. In all these cases, there is no need for a mutable accumulator / result holder. Consider the special case of string concatenation. In many environments (.NET, Java), strings are actually immutables. Why then allow an assignment to a string variable at all? Much better to use a builder class (i.e. a StringBuilder) all along.
我意识到，今天的大多数语言并没有默认我的愿望。在我看来，由于这个原因，所有这些语言都有根本性的缺陷。如果将它们更改为默认将所有变量视为只读，并且在初始化后不允许对它们进行任何赋值，那么它们的表达性、功能和易用性将不会受到任何损失。
