final case classUnreferenced[T[_[_]], A]() extends QScriptCore[T, A] with Product with Serializable
A placeholder value that can appear in plans, but will never be referenced
in the result. We consider this a wart. It should be implemented as an
arbitrary value (of cardinality 1) with minimal cost to generate (since it
will simply be discarded).
