Assume there is a string holding the address of an `uint64` type variable, can we parse this address back to an `*uint64`? 

For example:

```
i := uint64(23473824)
ip := &i
str := fmt.Sprintf("%v", ip)

u, _ := strconv.ParseUint(str, 0, 64)

```

`u` is `uint64`. How to get pointer out of this value?
