Clojure

Lack of built-in syntax for optional and keyword parameters in function definitions. Sure, you can add it easily enough, but that means library writers don't use it. Pervasive destructuring hasn't proven to be a good substitute yet Lack of method combination (before/after/around methods of the sort found in Common Lisp) Too much reliance on Java interop, e.g. there's no built-in file IO Sometimes I want static typing. This one isn't pure hate; I usually prefer dynamic, and attempts to mix the two have been largely unsatisfactory There's no built-in fast binary serialization format for the built-in data structures, though I hear people are working on it

以下是我不喜欢Java的一些地方(它不是我最喜欢的语言):

Generics type erasure (i.e. no reified generics) Inability to catch multiple exceptions (of different types) in a single catch block Lack of destructors (finalize() is a very poor substitute) No support for closures or treating functions as data (anonymous inner classes are a very verbose substitute) Checked exceptions in general, or more specifically, making unrecoverable exceptions checked (e.g. SQLException) No language-level support for literal collections No type-inference when constructors of generic classes are called, i.e. the type parameter(s) must be repeated on both sides of the '='

Lua

我喜欢用Lua编程，但下面是让我头疼的事情:

没有办法用这种语言编写API——不像C .h文件或Java接口 语言有一流的功能，但有人忘记告诉设计库的人。 编写函数的语法太重量级了。 语法分为语句和表达式。 表达式形式是贫乏的:没有let形式，没有真正的条件表达式，……

尽管如此，我还是坚持认为Lua非常棒:-)

我觉得最喜欢的语言是不可能选择的。动态类型和静态类型不能进行比较，所以我只列出我使用的是哪一种类型

C++:

Template metaprogramming syntax is ugly. An implicit ::value would make it much more concise ->. Why can't the compiler figure out that I'm doing a ptr.thing and just do -> for me? I hate whitespace. So the whole vector<vector<int>> has to be vector<vector<int> > makes me get the jitters and then I can't focus whenever I see that line of code and I end up trying to figure out a way to use int[][] or something Macros. I personally love the concept of macros. But with C++, I that the system is a hack I'm a hater of ;

Python:

字符串是不可变的。这样我就不能用string[4]="b" 通过引用隐式复制列表。哪个泄漏到[[0]*width]*height问题 缺少尾递归(每当我输入错误递归函数时，我必须安装IDLE以避免吐出1000条错误消息) 字典键不接受列表/字典 缺乏深度范围。当我做一个列表推导时，我不希望其中的变量影响到外部作用域

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 !

Perl 5:

All the really good stuff nowadays seems to require mod_perl, which has low availability everywhere I want to go. Some really incredible functionality can be encapsulated in modules, but what is under the hood is often fragile or frightening: source filters, typeglobs, whatever Moose is doing... DateTime is brilliant but still made some very bad design decisions (not returning a stopwatch duration when subtracting two DateTime objects) Dual-lifed modules in core and on CPAN still cause conflicts module authors still put interactive stuff in their module configuration scripts so that they can't be automatically installed
