UnmovableClass, UncopiableAndUnmovableClass

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

struct CopiableClass: protected UncopiableAndUnmovableClass {
  CopiableClass(CopiableClass const& from)
    : UncopiableClass() // , ...
    {
      // ...
    }
};

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

struct CopyAssignableClass: protected UncopiableClass {
  CopyAssignableClass& operator= (CopyAssignableClass const& from)
    {
      // ...
      return *this;
    }
};
