标准库的奇怪之处:它并不总是显示最佳实践，而且文档不足 硬编码FunctionX, TupleX类 缺乏属性:getter和setter是分开的，这违反了DRY，并且使得像FRP这样的事情几乎不可能实现 需要= _来初始化属性

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.

Python 3

both tabs & spaces allowed for indentation And you'd think people learn from the past (Makefile). Just pick spaces and forbid tabs. YAML got it right. lack of popular third-party libraries The standard library is great, but a lot of what makes Python 2 so powerful lies in the third-party realm. Python 2 got this right :-). IEEE floats Floating points in programming languages are confusing because they're different from the way we use them in math. Instead, the number operations should be viewed as expressions that are only converted to a decimal point format when needed (i.e. printing to a screen). Maple and Mathematica did this right I think. the character set for identifiers is too restricted list.empty? is better than list.is_empty or even len(list) != 0. Similarly, process.kill! would be better than process.kill. Ruby and lisp got this right. when calling a function you must always write parentheses It would be nice if we could omit them in unambiguous cases. How is it again? dict.items or dict.items()? Ruby got this one right, too.

C#

Cannot create a reference (var &t = struct) No local scope destructors (IDispose comes close but its not the same) ToString, i almost dislike that every object has it but it turns out i dislike everything using it like string.format does. I rather have things that accepts a certain type (like ints, floats, text, chars only). So instead of passing in any object i need to pass in something with a implicit typecast or interface. I ended up writing something like this to safely escape text for html which worked great. Cannot use a virtual typecast (blah)obj; does not work if obj does not inherit/has an interface of blah. Simple workaround is to supply an interface with a convert function. Has no local creation. Instead of writing var o = new Item(); i would like to write (something like) Item o() (with an automatic dispose if it has one).

C#

1)缺乏为值类型编写泛型的实际能力。例如，任何白痴(好吧，大多数白痴)都可以编写一个例程，用c++计算int, float, double等列表的标准偏差，它写起来很简单，易于阅读，并作为快速的非泛型代码执行。我认为，如果你能用c#写一些东西，接近于达到这三个中的任何一个，而在其他两个上又不荒谬，你就是一个真正伟大的程序员。

2)协方差和反方差，尽管这被添加到4。

3)非常糟糕的LINQ文档(好吧，并不是语言的一部分)。

4)尝试使用foreach/迭代器，当我每次都想做同样的事情，除了上次略有不同(如连接一串字符串与逗号之间的单词和最后两个)。如果我用一个IEnumerable来写它，它很难写和读，而用一个for (int I =0 I <…)它并没有好到哪里去，而且效率更低。

5)我知道我会收到抱怨，但是缺少受控的例外。这并不需要像在java中那样实现(框架开发人员确实提出了一些很好的观点，为什么他们没有这样做)，但我很乐意看到编译器警告不喜欢受控异常的用户可以关闭。

默认情况下弱类型(Option Strict修复了这个问题，但默认情况下没有启用) 在方法上不需要括号(myFunction而不是myFunction()等等) 是否使用括号来定义数组/使用(myArray(12)而不是myArray[12]) 不支持直接递增(i++) 是否支持遗留的On Error关键字和整个VB6-Namespace
