Common Lisp:

关键词往往太啰嗦。 库支持是可怜的。 在希望更严格地处理内存的操作系统中不能很好地工作。 没有与操作系统交互的良好工具。 “循环”功能没有很好地定义，当然看起来也不像Lispy。

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。

Python:

Global Interpreter Lock - Dealing with this complicates parallel processing. Lambdas functions are a bit clunky. No built-in ordered-dictionary type. Depending on how Python is compiled, it can use either UCS-2 vs UCS-4 for the internal Unicode encoding, many string operators and iterators may have unexpected results for multi-byte characters that exceed the default width. String slicing and iteration depend on the bit width rather than checking and counting characters. (Most other programming languages do similar things as well and have similarly odd behavior with these characters.) There are inconsistencies surrounding GUI frameworks for Python.

Ruby:

太慢了 自负的群体 这不是闲谈 在nil上调用方法时出错，而不是返回nil à la Objective C 非线程

C++:

缺乏象征意义。 过度迷恋C语言的兼容性。 极其复杂的预处理器。 模板错误几乎是不可理解的。 没有垃圾回收。

C++

编写一个简单的代码片段要花很多时间。 对于(std::vector::const_iterator iter =[…] Vector.remove()不移除。 Vector.push_front()不存在。 头文件 没有λ 如果至少有一个虚函数，则没有自动空虚析构函数。
