By the way, here's my draft code for vector calculus:

  http://beshenov.ru/maxima/vector-2008-11-15.tar.bz2

It uses some ideas from the vector3d.mac by Walter Eastes.

It still treats lists as (3D) vectors (and works with "nonscalar" 
symbols as well), but I think that "listarith" is a total mess when it 
comes to the real vectors. It could be better to use vector(x,y,z) 
instead of [x,y,z].

The products are denoted as

  x dot y
  x cross y
