[boost] null

Just wondering if there was any interest in a better null, or if such a 
thing existed in boost already.  The code is relatively simple:

class null
{
public:
    explicit null ( void * )
    {
    }

    ~ null (  )
    {
    }

    template < typename T >
    operator T * (  )
    {
        return 0;
    }
};

null null ( 0 );

Example usage:

int * p = null; // ok
int i = null; // error: null cannot be converted to an int
