As I'd pointed out before, I suspected that there was a namespace problem, and your suggestions are good for determining if that's the case. The problem is, what do I do if I make that determination? You passively mentioned this:

This is why you need to declare your package first before using Exporter style modules.

Can you elaborate on this? I assume this is something I didn't do, and I don't quite understand how to change the code to meet this requirement. You so quickly mentioned, almost as an aside, that it sounds as though you don't suspect it to be an explanation for the behavior.
