Continuing foreach in Queries

Inspired by Shortest path syntax Get started with Dgraph I thought of a new way with foreach in mind, for query in Suggestions to Improve GroupBy example

In this case foreach would be a reserved word.

{
 var(func: has(group_name)) {
    member @groupby(first_name) {
    Group as count(uid)
    }
  }
# It gets the name of the "block" 
# from "first_name" predicate
  foreach(func: uid(Group)) {
    first_name
    last_name
    Total_with_this_name : val(Group)
  }

}

The result

{
  "data": {
    "q": [
      {
        "Michel": [ 
              {
                "Total_with_this_name": 6
              },
              {
                "uid": "0x1",
                "first_name": "Michel"
              },
              {
                "uid": "0x6",
                "first_name": "Michel"
              },
              {
                "uid": "0x8",
                "first_name": "Michel"
              },
