[boost] Bit reference class?

Seeing the dyn_bitset code, I wonder if we should have the bit_reference
class as a separate library, that other bit-packing code can use.  The
structure could be like this:

template < typename BlockType >
class const_bit_reference
{
    BlockType const &  ref_;
    std::size_t const  pos_;

public:
    const_bit_reference( BlockType const &, std::size_t );

    operator bool() const;

    bool  operator !() const;
};

template < typename BlockType >
class bit_reference
{
    BlockType &        ref_;
    std::size_t const  pos_;

public:
    bit_reference( BlockType &, std::size_t );

    operator bool() const;
    operator const_bit_reference<BlockType>() const;

    bool  operator !() const;

    bit_reference &  operator =( const_bit_reference const & );
    bit_reference &  operator =( bit_reference const & );
    bit_reference &  operator =( bool );

    void  flip();
};
