That statement is not subject to change. Note that that statement does not say that if p1 and p2 are pointer values, and that p1 == p2, that uintptr(unsafe.Pointer(p1)) == uintptr(unsafe.Pointer(p2)). You must not take intuitions from computer hardware into a managed memory language like Go. The rules about the safe use of pointers converted to uintptr are written down at https://golang.org/pkg/unsafe/#Pointer . Doing anything not explicitly permitted there is unsafe, where unsafe means that your program may suffer from arbitrary memory corruption and may crash at any time.
