Construct a new WhereFalse object from a sequence of transformed items from the true branch of the predicate and the not yet transformed false branch sequence.

Parameters

when_true_queried	Queryable that is the transformed sequence of true branched items of the predicate.
when_false_items	Sequence of false branched items of the predicate to query over.
