我不敢相信，我最讨厌的Python竟然还没被提到:

(Prior to 3.x) Relative imports look like absolute imports. import foo Does this import foo from the directory you're standing in or from the sys.path? Zipped eggs, leading to a sys.path full of shite. Zipped eggs means you can't use grep and find (to among other things debug problem 1)! Fortunately, there's pip. Use pip. Some of the included batteries are unpythonic. It grates to use them. Might be the fault of distro's and packagers, but still: sourcefile-encoding set to fscking ASCII on install/compile. WTF? Means I have to put the "# coding: UTF-8"-stuff in every single .py I ever make.

Py3k解决了我的其他几个讨厌的问题，例如坚持字符串是unicode的，8位的东西是不同的……

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。

数组部分选择不能给你所要求的。

[1]给出一个元素 A[1:2]给出一个元素，而不是[A [1]， A [2]] A[1:3]给出2个元素

我讨厌这样，但可能是因为我大部分时间都在Verilog上工作。

C++

Strings. They are not interoperable with platform strings, so you end up using std::vector half of the time. The copy policy (copy on write or deep copy) is not defined, so performance guarantees can not be given for straightforward syntax. Sometimes they rely on STL algorithms that are not very intuitive to use. Too many libraries roll their own which are unfortunately much more comfortable to use. Unless you have to combine them. Variety of string representations Now, this is a little bit of a platform problem - but I still hope it would have been better when a less obstinate standard string class would have been available earlier. The following string representations I use frequently: generic LPCTSTR, LPC(W)STR allocated by CoTaskMemAlloc, BSTR, _bstr _t (w)string, CString, std::vector a roll-my-own class (sigh) that adds range checking and basic operations to a (w)char * buffer of known length Build model. I am sick to death of all the time spent muddling around with who-includes-what, forward declarations, optimizing precompiled headers and includes to keep at least incremental build times bearable, etc. It was great in the eighties, but now? There are so many hurdles to packing up a piece of code so it can be reused that even moms dog gets bored listening to me. Hard to parse This makes external tools especially hard to write, and get right. And today, we C++ guys are lacking mostly in the tool chain. I love my C# reflection and delegates but I can live without them. Without great refactoring, I can't. Threading is too hard Language doesn't even recognize it (by now), and the freedoms of the compiler - while great - are to painful. Static and on-demand initialization Technically, I cheat here: this is another puzzle piece in the "wrap up code for reuse": It's a nightmare to get something initialized only when it is needed. The best solution to all other redist problems is throwing everything into headers, this problem says "neeener - you cannot".

诚然，其中许多内容超出了严格的语言范围，但在我看来，整个工具链都需要进行判断和发展。

Python:

Too slow! list operations don't return the list, so you can't do list.append(4).append(5). (I mean a reference to the same list, not a copy). This is a minor gripe; it's only come up a few times. statements don't return values (if, print, while, for, etc). This is only a problem when dealing with lambdas. lambdas can only be one expression. There's no real need for this restriction, as they are equivalent to functions in every other way. What if I want a button press event which calls two functions? I'd need to create a named function to supply that functionality to an action listener, while doing "lambda: f1(); f2()" would not hurt. you can only put standard a-zA-Z_0-9 as names. Having functions like "true?" and "+" would be great. Of course, this could lead to terrible obfuscation, but I'm not saying we immediately rename all functions to "p@$%3". Which do you find clearer to read: "dec2bin" or "dec->bin"? ("store_results" or "storeResults") or "store-results"?
