You don't need two data members.
According to Andrey Semashev (to whom I credit the technique to, and should've cited in the above post), you do need two data members, as some compilers interpret a pointer-to-first-member as equal to 0 (i.e., convertible to false). I honestly don't know if such compilers exist or are technically allowed to do that... - Jeff
