It has, theoretically, a 128 bit virtual addresses. Everything is an object. It has the single level storage so there aren't really any "disk files" as such. And once an address has been associated with an object, that address will _never_ again be used for some other object. So when an object is freed, its address becomes unavailable. Thus it is impossible to access a freed object or accidentally use an old address to access a different object. -- Wasn't there something about a PASCAL programmer knowing the value of everything and the Wirth of nothing?
