1)如果不是x是"foo"(而不是<> "foo") 2)“OrElse”和“AndAlso”短路(而不是简单的“Or”和“and”，它们的作用不同) 3) Nothing(而不是Null)

Python

__init__ 有些库很笨拙，比如smtplib self必须在方法声明中!! (3.0之前)对unicode的支持有点差 缺少内联尝试捕获 没有直接引用"this"/current模块(相反必须使用sys.modules[__name__])

德国

我的母语……虽然它听起来比克林贡语更美，但它是一个语法地狱……

conjugations: even regular verbs have different forms for each person and time (with few exceptions)... Example: I see, you see, he/she/it sees, we see, you see, they see translates into: Ich sehe, du siehst, er/sie/es sieht, wir sehen, ihr seht, sie sehen. polite form of address: equals 3rd person plural, used to equal 2nd person plural in the middle age... I really hate the concept of distinguishing between "Du" and "Sie" for my philosophy is that each human being should be considered equal in the amount of respect for it deserves (I mean, what are swear words for, hm?) punctuation: show me a language that uses more commas regularly! missing suitable words: eg. there's no real German equivalent of "convenience" or any derivate of this word... in almost every case you just can't translate it into another German word and keep the meaning... instead you would have to make up a whole subset to describe it somewhat adequate... Anglicisms and Denglish: Sure, the English language has "Kindergarten" or "Poltergeist" and what not but the German language is overflowing with Anglicisms nobody needs... Even worse: We redefine some words we adopt, eg. in German "Handy" means a cell phone and has nothing to do with the adjective it is in English... There are influxes on grammar as well, leading to "Denglish" expressions (see linked article at Wikipedia) There's more, but I don't want to exaggerate this and those are my personal Top5 of what I hate about the German language...

Haskell。

默认情况下导入Prelude。 类型类的范围是通用的。 模块不是一流的。 类型不能依赖于值。 单子不统一Functor。

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。

C

字符串操作。

必须手动处理字符串缓冲区是一个容易出错的痛苦。由于如此多的计算实际上是移动和修改字符串(计算机并不像人们想象的那样用于大型数字运算)，因此能够使用托管语言或c++的字符串对象来处理这些非常好。当我必须在直发C时，感觉就像在流沙中游泳。
