Yes, that is correct.
I am somewhat more unhappy with having to use
   npla.matrix_power(M,n)
instead of
   M@@n
in other teaching settings (e.g., graph theory
and recurrence relations).

I am certainly not objecting to making `@@`
available.  It just seems much less important
than getting `@` asap.

Thanks,
