Python linear algebra module -- requesting comments on interface

[Szabolcs Nagy]

nice interface, but with 3d apps i prefer cgkit's approach, which has
vec3, vec4, mat3, mat4 and quat types with lots of useful functions for
3d graphics (like mat4.looakAt(pos, target, up) or mat3.toEulerXYZ())

there are other libs with similar types and functions:
cgkit (http://cgkit.sourceforge.net/)
pyogre (http://www.ogre3d.org/wiki/index.php/PyOgre)
panda3d (http://panda3d.org/)
