Is resize() guaranteed to respect geometric growth? I know it has for me in practice, but this made me question everything. And more generally, it's nice when you can do that, but it's not a substitute. From an API standpoint it seems really weird for reserve() and resize() to differ in what they set the target capacity to - the natural thing would seem to be that they should only differ in the initialization + resizing, not in the reservation.
