I don't know about the future. In some sense GPIOs are so smallish resources that errorhandling every call to read/write them seem to be a royal PITA. That is why I wanted to switch them to bool and get rid of the problem, but now I also see that maybe that was not such a smart idea, if errors do occur on the set/get_value path. Alexandre?
