Haskell:

惰性计算导致空间泄漏。 数字层次结构不是根据数学抽象构造的。 严格的单元IO会使调试更加困难。 大型实现处理I/O的方式似乎与标准不太兼容。(特别是，输出字符只输出低8位——然后构建代码，使用这个假设来执行二进制I/O。我吐!) ($)运算符的结合性可以被改变以使某些表达式更漂亮。

大多数问题都不会上升到讨厌的程度，有些人试图解决或为每一个问题构建可靠的变通办法。

编辑:关于第5点有些困惑。特别是有些人似乎认为我指的是论证的顺序，但我不是。我不解释我的意思，我只想让人们去下面的链接http://hackage.haskell.org/trac/haskell-prime/wiki/ChangeDollarAssociativity，它很好地表达了我的意思。

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)。

R

不是我最喜欢的语言，但我经常使用它，有很多抱怨……

S3对象只是美化了的列表，S4类仍然将所有数据公开给用户 赋值操作符可以是<- ->或=，参见Mike Dewar的咆哮 我的。var是一个非常令人困惑的OO语言变量命名约定，参见谷歌的风格指南 我不应该后悔使用循环 神秘的错误消息

C++

cryptic error-messages when templates are involved lack of template constraints (many cases can be worked around with template metaprogramming, but this will result in unreadable code (at least for average programmers) in most cases) pointer to member-function syntax c++ standards committee should release offical standards more often (or at least release separate updates to the standard library itself), i mean really TR1 was released 2005, and we still dont have a shared_ptr, bind and alike in the standard library. -

EL -表达式语言，${…}和#{…JSF 2.0 Facelets用于从底层Java代码中提取数据。

All the fun things, like method calls with parameters and annotation based naming is only present in the EL in Java EE 6 which is only available in Glassfish v3. It is a royal pain to 1) get the right jars for an earlier Servlet 2.5 container, and 2) getting them to work without interfering with any previous implementation available in the container. Having only an earlier version of JSF like 1.2, takes away the method calls and leave you to work with f:setPropertyActionListener - http://weblogs.java.net/blog/2009/07/22/say-sayonara-spal - which, trust me on this, is not very nice. The EL parser has no idea of where the snippet it is to parse and interpret came from, so you tend to give everything an id so you at least can identify which tag made it grumpy. Eclipse gives a warning at every EL method call as it is JSF 1.2. only too.

Lua

If you do foo.bar(1,2) then 'self' is nil inside the bar method. You must remember to do foo:bar(1,2) instead. I'd rather have that switched ('self' should be defined by default unless you use the ':' operator, or you call a function that isn't a method). Variables are global by default. I'd rather ditch the 'local' keyword and have a 'global' one instead. Undeclared variables are assigned the nil. I'd rather receive an error message. You can sidestep this by manipulating the global env's metatable, but I'd rather have it implemented by default and be able to deactivate it. Multiple returned values on parameters are not handled very nicely. Say you have a function foo() that returns 1,2,3 (three values) and bar() returns 4,5 (two values). If you do print(foo(),bar()) you will get "1,4,5" ... only the "last" tuple is expanded on calls. The # (table length) operator only works in tables indexed with continuous integers. If your table isn't like that and you want to know how many elements does it have, you need to either parse it with a loop, or update a counter each time you insert/remove an element from it.
