I wonder about the usefulness of pointers.
A use-case for pointers is: std::unordered_map< T*, std::weak_ptr<T> > Where the T is constructed via std::make_shared. Note: If any std::weak_ptr references the control block created by std::make_shared after the lifetime of all shared owners ended, the memory occupied by T persists until all weak owners get destroyed as well, which may be undesirable if sizeof(T) is large.
