It's not simply a matter of protecting yourself in the present. The
major advantage of using accessors is that you aren't committed to
exporting data symbols in the future. To maintain binary compatibility,
you'd have to keep those data symbols exported (and, one would hope,
make sure they are correct ;) even if you completely change the way your
class is implemented and don't actually need those variables anymore for
your implementation! By using accessors, you can more easily change the
implementation again and again without accumulating a lot of useless
baggage.
