Hacky way to find distance (number of hops) from one node to other nodes

Following that query, I think if we had loops this would be much more precise.
Bellow an idea of a loop generating a shortest path on each person found. And the _weight_ tells us the distance automatically.

Feature: Add foreach() function

{
   var(func: eq(name, "Anurag")) @recurse(depth: 3){
    all as uid
    knows
   }
	targets as var(func: uid(all)){
		name
		city
		age
	}

 q(func: foreach(in: targets, title: name)) {
  A as var(func: eq(name, "Anurag"))
  M as var(func: eq(name, this.name))

   path as shortest(from: uid(A), to: uid(M), numpaths: 2) {
    knows
   }
   path(func: uid(path)) {
     name
   }
 }

}

Result
