recently came across an interesting feature to C++11: std::tie. One of the features I love about python is that you are able to return multiple values from a function. These get returned in a struct

#include #include class A{};class B{public: void setA(std::shared_ptr spa) { std::cout << spa.use_count() << std::endl; spA = spa; std::cout << spa.use_count

a shared_ptr implements some comparison operators- e.g., a shared_ptr implements the “- but, it doesn’t invoke “‣ instead, it just promises a stable, strict ordering‣ given two shared pointers
