Contrary to what I've just said, you could implement comparisons using the pointers alone and excluding the bits. I think this would be reasonable. Consider a comparison to nullptr (or (void*)0).
Would it be better to make the pointer_plus_bits convertible to a boolean based on the value of the pointer being stored? This would allow it to be more like to a pointer being that you could, as many people do, put it inside of an if statement to check to see if its null.
Actually, yes. I think that would be a better idea :) Andrew Sutton andrew.n.sutton@gmail.com
