query untyped relationships

[CrystalMethod]

Given a simple data model as follows:

interface Person {
    Collection<Person> getFriends()
}

and a Cypher Query

MATCH ()-[r]->() RETURN r

or Gremlin Query

g.V.outE()

an XOException will be thrown

Cannot resolve relation from discriminator 'FRIENDS'

what is absolutely right because the relationship is untyped. But I wonder if it wouldn't be better to return some kind of "untyped relationship" object that only contains getId() and possibly getFrom() and getTo().
