Dear Christoph,

We do at several points. E.g.
s1 * A * s2 * B * s3
is optimized to something equivalent to
(s1*s2*s3)*(A*B)

o.k. thanks, I'll better stay with my for loops.

You may be interested in this feature-request:

That's actually a different story. I don't need quaternion for that,
my types are actually Grassmann variables combined with a floating point.
Best regards,
Peter
