C:

Lack of distinction between function pointers (executable) and data pointers (you really don't want to execute this). Extreme unreadability. Making code look like it does what it does is orders of magnitude more difficult than making it do the task in the first place. Lack of clear support for lisp-think. Doing functional things is possible, barely, but it's not clear. Serious inconsistency between libraries about how error codes are returned. Antiquated string handling. The strings aren't strings, they're null-terminated blobs. This is all manner of wince-worthy.

Lisp:

()需要按shift键。每次我口齿不清的时候，我就把它和[]交换。

c# / .net:

Classes should be sealed by default There should be no lock statement - instead, you should have specific locking objects, and there should be methods such as Acquire which return disposable lock tokens. Corollary: there shouldn't be a monitor for every object. GetHashCode() and Equals() shouldn't be in System.Object - not everything's suitable for hashing. Instead, have an IdentityComparer which does the same thing, and keep the IComparer<T>, IComparable<T>, IEqualityComparer<T> and IEquatable<T> interfaces for custom comparisons. Poor support for immutability Poor way of discovering extension methods - it should be a much more conscious decision than just the fact that I'm using a namespace.

这些都是我想出来的，明天问我，我会想出一个不同的5个:)

Emacs Lisp

目前还没有足够的商业市场让人们全职用elisp编码 GNU Emacs vs XEmacs不兼容 Scheme中的嵌套函数很整洁，我希望elisp有[1]的概念 用于简单遍历列表的do循环或其他一些工具不是标准的(当然，您现在可以使用lambda进行映射)[1] (function (lambda(…)))[1]应该有一个简写

当然，Lisp的一个美妙之处在于，用一行代码在你自己的代码中修复这些问题并不难。但这并不是与生俱来的，这让我很恼火。

好的问题;我有点不好意思，因为我想不出更好的东西来恨，但说实话，法官大人，没什么好恨的。

我可以为Python添加另一个:

给定一个列表l = [l1, l2，…]， ln]，那么repr(l) = [repr(l1)， repr(l2)，…， repr(ln)]，但str(l) != [str(l1)， str(l2)，…， str(ln)] (str(l) = repr(l))。之所以这样做，是因为列表中可能有模糊的条目，如l = ["foo]， [bar，"， "]，["]， str(l)将返回"[foo]， [bar，]，[]"，这“可能会使用户感到困惑”。然而，这使得str不可能仅用于转储数据，因为list杀死了“仅以可读格式转储数据”。Augh !

VBA(因为你认为你的语言不好)

Whitespace inside a line is rigidly enforced. Statements just end, and require a " _" to break to the next line, but not every line can be broken. No ++,--,+=,-= statements. Seriously? Arrays can begin at any index, not just 0. Some types (i.e.: fixed-point "Decimal" value) must be subtypes of Variant, and aren't available as their own type. != and <>. "=" is used as both comparator and assigning, instead of splitting into "=" and "==". "Option Explicit". UI hasn't been updated since 2000. Office2k7 didn't upgrade to VB.NET Most object models are non-sensical and overly verbose.

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。
