box has arrow, parcel tag has string/thread. We could attach an arrow instead of a string to the parcel tag. The box does not contain anything inside (we can attach the arrow outside the box -- nothing changes). If the box does not contain anything then we could use a parcel tag instead. -- https://mail.python.org/mailman/listinfo/python-list
