Comment (by nthiery):
Thanks for exploring how to clean this up.
Just for the record: we have had left/right/bimodules since 2009 and
probably even before. Also, at this point, they are just categories over a
base ring, not functorial constructions.
One thing to check is how this was handled in Axiom. MuPAD was roughly as
here: on the lousy side in the non commutative case.
