    extends StringLocalStep<S,​E>
    Reference implementation for the local scope of the toUpper() step, a mid-traversal step which returns an upper case string representation of all elements inside the incoming list traverser. Null values are not processed and remain as null when returned. If the incoming traverser is not a list or a non-String list then an IllegalArgumentException will be thrown.
