    could easily cache the identity and charpoly coefficients using
    the nontrivial factor. On the other hand, it's nice that we can
    test out some alternate code paths...

+4. Conjecture: if x = (x1,x2), then det(x) = det(x1)det(x2). This
+   should be used to fix the fact that det(x) is monstrously slow in
+   Cartesian product algebras, and thus randomly in the doctests.

+5. Add dimension bounds on any tests over AA that compute element
+   subalgebras.
