Hmm, I figured the two "parent" references do mean the same thing,
ie the immediately surrounding syntactic construct. While I won't
fight hard about it, I don't see an advantage in naming the new
field differently. We could make the comment be
/* outer level's alias for this query */
if that helps any.
