We just assume some abstract type `Pointer`.) We cannot represent a byte of a pointer as an element of `0..256`. -Essentially, if we use a naive model of memory, the extra "hidden" part of a pointer (the one that makes it more than just an integer) would be lost whne a pointer is stored to memory and loaded again. +Essentially, if we use a naive model of memory, the extra "hidden" part of a pointer (the one that makes it more than just an integer) would be lost when a pointer is stored to memory and loaded again. We have to fix this, so we have to extend our notion of a "byte" to accomodate that extra state. So, a byte is now *either* an element of `0..256` ("raw bits"), *or* the n-th byte of some abstract pointer. If we were to implement our memory model in Rust, this might look as follows: -- 2.30.2
