+1 to a catalog (using lazy imports as much as possible!) +1 to removing not-very-common categories from global namespace
Not convinced about the alias AdditiveCommutativeGroups = CommutativeAdditiveGroups. I believe it will just add confusion, and wildcards are our friends (as in *AdditiveGroups*?). Besides, as was mentioned, one can already get something close with AdditiveGroups().AdditiveCommutative() Open question: do we want the catalog to contain things like the short hands CommutativeRings(), when we already have Rings().Commutative()? When I implemented axioms, I left CommutativeRings around mostly with backward compatibility in mind. Cheers, Nicolas -- Nicolas M.
