C++

The inconsistencies in the libraries related to char* and std::string. All C++ libs should take std::strings. Characters are not bytes with respect to iostream. I do a lot of byte-oriented work. Having a "byte" type and a "character" type would significantly make it simpler. That, too, would permit scaling to Unicode somewhat easier. Bit operations should be easy on a value. I should be able to access and set the n'th bit of a value without playing AND/OR dancing. The lack of a standardized interface for GUIs. This is where Microsoft has really been able to position themselves well with C#. A standard interface binding that OS makers provide would go really far for my work.

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。

Erlang

没有静态推断 就像在哈斯凯尔发现的一样。这 会导致运行时错误和一个 有认真写代码还是使用 透析器(1)发现 差异。动态类型是 慢的:也被认为是慢的; 与C、Java等语言相比，它几乎是未知的; 的lists(3)模块有时相当精简 我缺少用于列表处理的有用函数 (就像在数据。例如Haskell中的List); 让我在每句话的结尾都加上 在从句中，和。最后是后者。

PHP:

荒谬的assert()函数…它对里面的代码运行eval() ?>标签删除了它后面的换行符?! 奇怪的数字字符串处理(尝试将它们作为数组键) 令人痛苦的unicode支持似乎将不再被PHP 6解决 入门成本低意味着95%的人给PHP程序员起了一个可怕的名字——试图在这5%中找到一个人来雇佣是疯狂的。

我讨厌所有语言的五件事(至少就我所知):

Does what I say/type, not what I mean Will undoubtedly meet people who think they are experts in the language, but just make a mess of it (e.g. people who insist that removing comments/unused local variables will speed up execution time for a program) Unless the language is obsolete, then it will probably continue to evolve (either the actual language, or the concepts behind using it effectively) requiring you to actively develop with it so as to not fall behind. Can't modify the lexer/compiler (add in own context sensitive grammar) No perfect language (every language is missing some sort of useful feature that usually is either impossible to simulate, will unavoidable have an ugly interface or just require far too much time to implement and get it right)

Ruby。

Strange scoping rules - variables, constants, and methods each behave differently from each other. The rules change also depending on which keyword you used to create a closure. Or on whether you're in a class, eigenclass, object, module, or module's self. Then there's instance_eval, which changes the rules to a different set of rules. And they change again when a module is "included" or "extended", which themselves do different things to scope. And some sets of rules can't be emulated by metaprogramming, so you have to use eval. Unless you're on ruby 1.9, where all of this is different. Namespacing is basically useless. If you have Foo::File, then the stdlib File is probably broken for all of Foo. require statement is broken. If two files require eachother, the behavior of those files can change dramatically depending on which is loaded first from elsewhere. libraries change APIs dramatically and suddenly, so you have to require specific minor revision numbers of all of your dependencies. For every single ruby application on your system. The rubygems package system overrides "require" rather than putting files in the search path - because why use a system when you can replace it?
