UncopiableClass, UncopiableAndUnmovableClass

A class derived from this one can still be moved with an explicit effort. For example, to enable move construction:

struct MoveableClass: protected UnmovableClass {
  MoveableClass(MoveableClass&& from)
    : UnmovableClass() // , ...
    {
      // ...
    }
};

the default constructor of the base class can be called explicitly instead of the move constructor. To provide a move assignment operation,

struct MoveAssignableClass: protected UnmovableClass {
  MoveAssignableClass& operator= (MoveAssignableClass&& from)
    {
      // ...
      return *this;
    }
};
