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! ;-)

我使用Java，我最大的不满是字符串操作的低效率。当你使用+运算符时。说真的，难道编译器不能计算出我添加了多少字符串，然后在后台为我生成StringBuffer的东西吗?

通常，使用+的代码比StringBuffers操作序列更具可读性。

另外，我讨厌本机数组和集合框架之间的冗余。. toarray()的语法极其丑陋。

但这只是因为VB6毒害了整整一代程序员

我在一个曾经是VB6商店的VB . net商店工作，而在这里工作的每一个曾经是VB6开发人员的人都顽固地拒绝学习任何关于. net的知识。他们编写的代码就像VB6一样，他们的应用程序就像VB6应用程序一样糟糕。我的老板非常不鼓励使用LINQ，因为她担心其他人很难理解，这是事实，因为没有人想要理解它。

我认为如果微软只使用c#，我们会过得更好，这让我很难受，因为我认为花括号远不如VB的冗长结束语句。

Common Lisp:

关键词往往太啰嗦。 库支持是可怜的。 在希望更严格地处理内存的操作系统中不能很好地工作。 没有与操作系统交互的良好工具。 “循环”功能没有很好地定义，当然看起来也不像Lispy。

Perl代表了一种可怕的语言。

No "public" or "private" or "protected" declarations/definitions. The "my $variable_name;" does not declare a global outside of a subroutine. The "my $variable_name;" gets accessed by subroutines but "use strict;" or other "use " creates warnings. Function prototypes end up unexplained, undemonstrated, unwanted, or some other excuse. Overzealous symbol use ends up "cool and quick" when reading globs of symbols. When one gets hot they like to stay hot, and need nothing to cool them. After a week of Perl, I end up unable to write a function and prototype it. What exactly is a module and does it actually NEED a ".pm" extension? If you want to create a public variable and access it from inside a subroutine, how do you accomplish this without creating a warning? Where do you find some neat scripts that teach one some neat Perl?

C是我最喜欢的，但也很糟糕。

It has the worst pre-processor ever. Why didn't they use something like m4? The whole header vs source file model is broken. Pascal got it right with units. It needs case ranges in the switch statement. Unions and casts from void* break the type system. This makes garbage collectors impossible. No nested functions. GNU C has this, but it should be standard. No boundary checking for allocated memory. There are tools that discover this but they don't detect errors where a piece of code miscalculates an address and writes to an allocated region which isn't related at all. I hate the whole pointer arithmetic. No bounds checking for arrays. Too many issues regarding portability. Even wchar_t differs across platforms.
