This morning someone asked about dereferincing a pointer to a pointer to a
pointer
At first nobody had ever thought about, let alone knew the answer, but some
example code was shown, and sure enough ***val is possible
```
package main
import "fmt"
func main() {
a := 0
b := &a
c := &b
UltimatePointOne(&c)
fmt.Println(a)
}
func UltimatePointOne(n ***int) {
***n = 1
}
```
On a lark a go playground example was tried to find what the maximum * is
in Go
https://go.dev/play/p/YhibY3p7TSD
There's 28 there, but it's not the limit
Does anyone know what the upper bound on this could be?
256 * ?
32k * ?
