Ok. I think I got it. Vectors are things that depend on position inside
buffer and scalars are things that don't, am I right? In that sense we
don't have any vector-vector multiplication. Both async_gen_syndrome()
and async_pq() use constant coefficients. So I don't really understand
the problem here.
