False positive with no unused variable rule

[jbttn]

Variables contained within objects are not detected by the "no unused variable" rule:

query Foo($a: String) {
  field(object: { a: $a })
}

"Variable "$a" is never used in operation "Foo"."

Any update on this, I am also facing similar issue with swift Graphiti Library.
