Example of using variable in mutation?

[tamethecomplex (Jeff Hull)]

For anyone looking to do something similar, here’s another working example in v0.8.3:

{
	ns as var(func: eq(VertexType, "Namespace")) @filter(eq(Name, "General"))
}

mutation {
  set {
    _:a <Name> "This thing" .
    _:a <Namespace> uid(ns)  .
  }
}
