It should probably be pointed out that LV already has a primitive called Array of Strings to Path, which does cover the basic functionality of this idea, although not with the same syntax.
I like it! like autoindexing a path to string array both ways! We have the ability to code the stuff nativily but, this is one where NI R&D might be able to add more "bullet-proofness" than the general population.
With some other changes to Build Path now "In Beta", any thought of progressing this idea as well? It would make sense to implement a growable node for both Build Path and Strip Path.
