VBA(含MS Office IDE):

1)文件不足 2)错误信息差 3)数组操作例程不足 4)必须重复DIM语句的类型 5)无法彩色打印(必须购买第三方插件)

C++

(除了lambda函数，我已经避免了Cpp0X中可用的东西)

不强制使用"this"访问成员变量，::GlobalFunction访问全局命名空间。 (更具体地说，算法中缺少lambda函数，将在0x thou中修复)中的所有内容 处理依赖文件/头文件和源文件 基本数据类型上的愚蠢名称(应该命名为uint8, int16等) const_cast功能

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. -

Objective Caml

Non-concurrent garbage collector. I can write multi-threaded programs all day long, but they're only ever going to get one of my eight cores at a time. This makes me sad. No type classes (or their moral equivalent). There's Furuse-san's GCaml, but it's A) not quite as good as type classes, and B) not in the INRIA distribution. Badly in need of a Cocoa bridge. Seriously. If I wrote more code with actual interfaces to DNA-based life forms, then I'd probably break down and write the damned thing myself. Why hasn't anybody else done this yet? Functors are abominable. Seriously, modules ought to be first-class values. There should be only one kind of function. Read Montagu and Rémy before you flame me for this. Should use LLVM for its back-end. Who do I have to murder to get OCaml to compile for my stupid little ARM6 core?

是的，我有一些问题。我仍然非常喜欢这门语言。这太棒了。

Python

那些我不理解的…

math.ceil() and math.floor() return floats, not integers (probably to avoid an integer overflow in the underlying C function - but why not cast to a Python long?) len() is a function not a method reload() is very limited, does not reload a module 9 times out of 10, only reloads an imported label if it is a module - i.e. cannot do from bar import foo; reload(foo) if foo is not itself a module Mutable default arguments have a single reference (why not a new instance each function call?!) All these underscored variables - if they are so private, how come we see inbuilt ones so much in code? Get a namespace! Strings are not mutable - maybe there is a good reason for this but I have come across many situations where I would like to tweak one particular character ...

那些基于实现有意义但令人讨厌的……

array.sort()不返回数组(我认为它发生在原地) 列表/生成器推导式不定义新的作用域(只是for循环的语法糖，对吗?)

以及几个在Python 3中修复的

默认为整数除法 Global只能引用顶级名称空间

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.
