When querying user list, how to judge whether has followed the user and return bool?

Users Dgraph

Hi @pandalive, we appreciate your patience.
As for your first query regarding bool values. One way that I and @ahsan could figure out is to use math().

EDITED:

{
  data(func: uid(0x3)) {
     name
     cnt as count(follows) @filter(uid(0x4))
     result: math( cnt == 1 )
  }
}

Meanwhile, you can look at the RFC around the improvement.
Also, you can look at the discussion related to custom variable blocks.
