MEL(玛雅表达语言):

Single dimensions arrays: Forcing me to manually sync two or more lists, or use delimited strings to simulate more complex data structures. Naturally, they're immutable too. Single threaded and slow: Causing the entire Maya application to hang while it completes a task. Bonus points for not being able to kill long operations, instead having to close and re-open Maya. Script sourcing paths aren't recursive: Meaning every directory you want to store scripts in must all be added to the script path. No namespaces: Forcing the inconsistent use of naming conventions to make sure global procedures don't collide. Modal commands: Each command is modal, meaning the Create, Modify, and Query operations are all handled by setting flags. This also forced the developers to cause most of the commands to return arrays Inconsistent command style: Most array commands actually return arrays, but the Tokenize command has to take an array as a reference which it then populates, rather than spitting out an array. This among other inconsistencies.

这些以及其他几个原因是AutoDesk采用Python作为次要脚本语言的原因，这带来了其他一些令人讨厌的因素:

并不是所有的MEL命令都受支持:大多数都受支持，但有时您会发现自己不得不使用MEL()函数来执行一些任意代码。更糟糕的是，你不得不对它进行所有烦人的逃避。 继承了模态命令风格:必须使用相同的create=True, query=True, edit=True的东西。

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。

Python

那些我不理解的…

math.ceil() and math.floor() return floats, not integers (probably to avoid an integer overflow in the underlying C function - but why not cast to a Python long?) len() is a function not a method reload() is very limited, does not reload a module 9 times out of 10, only reloads an imported label if it is a module - i.e. cannot do from bar import foo; reload(foo) if foo is not itself a module Mutable default arguments have a single reference (why not a new instance each function call?!) All these underscored variables - if they are so private, how come we see inbuilt ones so much in code? Get a namespace! Strings are not mutable - maybe there is a good reason for this but I have come across many situations where I would like to tweak one particular character ...

那些基于实现有意义但令人讨厌的……

array.sort()不返回数组(我认为它发生在原地) 列表/生成器推导式不定义新的作用域(只是for循环的语法糖，对吗?)

以及几个在Python 3中修复的

默认为整数除法 Global只能引用顶级名称空间

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。

c++缺乏好的重构工具，缺乏受控异常

Java缺少模板，缺少const关键字

我讨厌内梅尔的五个方面:

局部函数不能让步 编译lambda的能力有时取决于它是否内联 元组的值/引用类型语义不一致 数组下标和类型参数之间偶尔会出现歧义 缺乏普遍采用
