>      * TODO
>      * Translation Issues:
>      * 1. back references in filters. For e.g. testBackreference: 'DB as db Table where (db.name = "Reporting")'
>      *    this is translated to:
>      * g.V.has("typeName","DB").as("db").in("Table.db").and(_().back("db").has("name", T.eq, "Reporting")).map().toList()
>      * But the '_().back("db") within the and is ignored, the has condition is applied on the current element.
>      * The solution is to to do predicate pushdown and apply the filter immediately on top of the referred Expression.
