In the example, it looks like barsub() in that same package as foosub(), which is a method. If barsub() has nothing to do with that same package or object, it's in the wrong place. If the situation is different, then the example code has way too much detail, and we don't need to know anything about anything else than barsub().

I don't know what the original poster is doing, but it looks like an odd design. That's why I asked. I'm not trying to guess what the he is actually doing. I'm just asking why he's doing it that way, and I'll wait to see what he says, and then I'll know (which is sooner than never ;).
