Error Handling for DTM Data Elements

I would love to see more robust error handling for data elements within DTM. Currently, if you have a DTM rule that calls a data element, and that data element causes a javascript error, you lose tracking for that entire call, instead of just the data element. Ideally, I would want to see DTM place the call to the data element into a try() block and output the specific error if it fails via the DTM debug mode.
