If speed is what we are after, we could just use l1norm:

CAS> l1norm(3+4i)      → 7
CAS> l1norm([3+4i])      → 7

Indeed, linfnorm==maxnorm is inconsistent. It should return 4 for both. However, I don't want to make such a change, because it breaks my regression tests. You will have to live with this inconsistency.
