This member is added by an implicit conversion from RefutationReachedCommand[V] to
CollectionsHaveToParArray[RefutationReachedCommand[V], T] performed by method CollectionsHaveToParArray in scala.collection.parallel.
This conversion will take place only if an implicit value of type (RefutationReachedCommand[V]) ⇒ GenTraversableOnce[T] is in scope.
