Order matters in CSS transforms, e.g.

  transform: translateX(20px) rotateZ(45deg);

is different from

  transform: rotateZ(45deg) translateX(20px);

I think if people are messing around with this kind of operator, they're
prepared to get into the concept of commutativity.  (Obviously, they
shouldn't get different behavior depending on implementation, but I don't
think that was your point.)
