In digging thru code, I realized that @jeff’s rewrite/cleanup of the Utility Mapper ends up using a technique I’m going to modify/clone, to implement my idea above. (It calls multiple patterns, cycling thru them.) My multi-segment (ok, multimap) version won’t cycle, but will instead call different patterns, depending on the multiple maps and settings, either as a partial map or a renormalized map.
Kudos for his clean code techniques.
