Oh, you are right, sorry! I misread the code. I though TensorProductsCategory was a subclass of RegressiveCovariantConstructionCategory. Hmm, back to the discussion about option (a) or (b). The same question arises for CartesianProducts; do we want it to be regressive, like is the case of Quotients and the like. It's not exactly the same use case. Cheers, Nicolas -- Nicolas M.
