which is just tricky enough that you should probably add it as a test
case.    My implementation would have to change to handle it, but it
would be an easy change.  For some implementations, it could be a real
pain.  (Queries like { ?x rdf:type ?y } will be unable to return
complete answer sets.)

I'll consider no response a satisfactory response for this comment,
given its timing.
