Additions to utility.hpp?

I have suggestions to add classes to "utility.hpp."  They are like the
noncopyable class, except they are for the other automatic operators
(address and comma).

1.  unaddressable
    + blocks (unary) &
    + has private declarations (within a class/struct) of
        T* operator&();
        T const * operator&() const;

2.  default_inoperable
    + blocks = & ,
    + has private declarations (within a class/struct) of
        T& operator=( const T& );
        T* operator&();
        T const * operator&() const;
        T operator,( const T& ) const;
        template <typename U>
            U operator,( const U& ) const;

I don't know whether or not both forms of operators , or & are needed.  I
guess their (default) constructor and destructor would be protected and
inline and be defined to do nothing, like in noncopyable.
