REQUEST: List item replace

Registering another formal request for the List Replace component.  The old behaviour (pre 0.9) was perfect.  

New behaviour invalidates an entire list if no index values are passed to it.  Old behaviour simply passed the list untouched, which seems to make all kinds of sense to me.  I recently spent half an hour combing through a definition and reworking all of the List Replace sections.  Would love to see the old behaviour come back!

Thanks,

Marc
