If it has a property that transforms like angular momentum, and if it
contributes -- along with other forms of angular momentum -- to a
conserved quantity that transforms like angular momentum, then it is a
kind of angular momentum EVEN IF the electron has no size and therefore
no chunk of matter in circular motion.
