	(Sponsor this newsletter) Comment on GotW #89 Solution: Smart Pointers by J. J. Lee Is there any helper template to relieve pain from make_unique to make_shared, if I decide to change from unique_ptr to shared_ptr later? For example, template <class SP> class smart_ptr_switch { template <class... Args> static SP make_smart(Args&&... args) { if (SP is some kind of unique_ptr<T>) { return std::make_unique<T>(new T(std::forward<Args>(args)...)); } else if (SP is some kind of shared_ptr<T>) { return std::make_shared<T>(new T(std::forward<Args>(args)...)); } else { static_assert ??? } } }; So I can typedef my_smart_pointer to a std::unique_ptr first. If later I change typedef my_smart_pointer to a std::shared_ptr, I don’t need to change all std::make_unque to std::make_shared. If I call smart_ptr_switch::make_smart(…) and typedef std::unique_ptr my_smart_pointer, this method will return a result from make_unique. If I call smart_ptr_switch::make_smart(…) and typedef std::shared_ptr my_smart_pointer, this method will return a result from make_shared.
