Groovy和Grails

动态类型 约定优于配置，假设您了解约定 你讨厌春天的一切 你讨厌Hibernate的一切 [Groovy]跨集合的常见操作不是(但最近的版本对此进行了改进)

C

It's so flexible and powerful that it's really easy to write really awful, or downright dangerous code (or, if you prefer, "with great power comes great responsibility"). '=' for assignment, and '==' for equality; easy to confuse in 'if' statements. The implementation of a number of fundamental parts of the language are compiler-dependent; e.g. the size of the basic types, order of bits in bitfields, padding and byte order in unions. Bitfields aren't parameterisable (i.e. you can array of ints, but you can't have an array of bits). String handling could be improved.

Python:

Too slow! list operations don't return the list, so you can't do list.append(4).append(5). (I mean a reference to the same list, not a copy). This is a minor gripe; it's only come up a few times. statements don't return values (if, print, while, for, etc). This is only a problem when dealing with lambdas. lambdas can only be one expression. There's no real need for this restriction, as they are equivalent to functions in every other way. What if I want a button press event which calls two functions? I'd need to create a named function to supply that functionality to an action listener, while doing "lambda: f1(); f2()" would not hurt. you can only put standard a-zA-Z_0-9 as names. Having functions like "true?" and "+" would be great. Of course, this could lead to terrible obfuscation, but I'm not saying we immediately rename all functions to "p@$%3". Which do you find clearer to read: "dec2bin" or "dec->bin"? ("store_results" or "storeResults") or "store-results"?

C / C + +

缺乏完整的SWAP功能 模板的语法 你不能#define一个#define(没有多通道) 编译器之间的结构打包不兼容 Char是有符号的还是无符号的?

Java

边缘上的不变性 没有像c#一样的ref关键字 到处尝试/捕捉积木 运行时性能差 所有与字符串相关的东西

Python

没有“main”(我已经习惯了!) 强调关键词 有限的线程支持 用self代替this 缺少类似C/ c++的语法

不得不假设我们有语言。我们做什么?

Common Lisp

缺少提供更现代功能的标准库(套接字，线程，…) 是否可以使用映射到本机窗口系统的标准化UI Scheme将lambda表达式赋值给变量并将变量直接作为函数调用使用的能力看起来比APPLY for FUNCALL更整洁。我猜这是使用多个名称空间的副作用 标准化的库源代码级打包系统，以便可以从多个实现中轻松使用它们

我想知道强类型的口齿不清会是什么样子
