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:
I think this case itself can easily be handled by people casting T* to
std::uintptr_t.
I think bigger issue is that users can not do this when pointer is nested
inside a type.
E.g.
How can user hash
std::tuple
