I don't know. Sorry. As I said earlier, I don't have a good answer here. You should open an issue for this. For some reason it has not been a problem, perhaps because most code doesn't use the wrapper methods much. One reliable approach you could take would be to not call runtime.Callers(1) from a value method or from a method in a type that you embed into another type. But I understand that that is not a satisfactory answer.
