> Why did you write setters that return values?

int oldx = p.setx(newx);
dosomethingwith(p);
p.setx(oldx);

is quite a useful thing to be able to do. You can get the same deal with:

int oldx = p.getx();
p.setx(newx);
dosomethingwith(p);
p.setx(oldx);

but only at the expense of an additional function call.
