Why GitHub C++ Core Guideline says that global object better than singleton?
GITHUB C++核心指南说：
A global object is often better than a singleton.
我总是想相反。从那时起，C++中发生了什么变化？或者可能只是另一个打字错误？
这是避免同一指南集合中出现单例的原因：
I.3: Avoid singletons
Reason
Singletons are basically complicated global objects in disguise.
Example
1 2 3 4 | class Singleton { // ... lots of stuff to ensure that only one Singleton object is created, // that it is initialized properly, etc. }; |
There are many variants of the singleton idea. That's part of the problem.
我对作者意图的分析：
越简单越好。如果将全局对象隐藏在单例中并不能解决全局对象的问题(正如上面的指导方针所暗示的那样)，那么就没有必要使用伪装使代码复杂化。
