Oh, I see.  That could let you know whether the module you're investigating is the positive party, and thus the party that exported the value with the contract.  Good point.

That's additional information that I was already going to add for the contract system's use on the branch I'm working on, but if it would be useful to make it available at large, I can do that as well.
