为什么C++中的”this”指针是指针而不是引用？

c++reference

Why is the “this” pointer in C++ a pointer and not a reference?

为什么C++中的EDOCX1 0指针是指针而不是引用？

是否有我遗漏的用例使"this"作为指针比引用更有用？

如果没有，将它作为指针是否涉及到语言设计的含义/考虑？

从Bjarne Stroustrup的C++风格和技巧谈起：

Why is"this" not a reference?

Because"this" was introduced into C++ (really into C with Classes) before references were added. Also, I chose"this" to follow Simula usage, rather than the (later) Smalltalk use of"self".
