In order to generate the code for a switch statement the compiler must understand what it means for two values to be equal. For items like ints and enums, this is a trivial bit comparison. But how should the compiler compare 2...
make_unique and perfect forwarding
... ptr(new Type(...));. It does something that you cannot do without it.
In order to do its job, std::shared_ptr must allocate a tracking block in addition to holding the storage for the actual pointer. However, because std::make_shared allocates the actual object, it is possible that std::make_share...
