The allocator-extended copy constructor for any requires an arbitrary template parameter to be available in a type-erased context where the dynamic type of the contained object is known. This is not believed to be possible in C++.

If the allocator-extended copy constructor cannot be defined it questions the usefulness of the other allocator-extended constructors.
