[译]C++11中的通用引用
Universal References in C++11 – Scott Meyers 或许C++11中最重要的新特征是右值引用；右值引用是移动语义和完美转发的基础（关于右值引用，移动语义，完美转发可以参考Thomas Becker’s overview）。 在语法上，右值引用和标准引用类似，区别是使用两个&，这个函数使用了Widget的右值引用： void f(Widget&& param); 考虑到右值引用是使用“&&”声明的，似乎可以合理地假设类型声明中出现“&&”表示一个右值引用，事实并非如此： Widget&& var1 = someWidget; // here, “&&” means rvalue reference auto&& var2 = var1; // here, “&&” does not mean rvalue reference tem...
