-5. Compute the scalar in the general natural_inner_product() for
- matrices, so no overrides are necessary.
-
-6. The main EJA element constructor is happy to convert between
- e.g. HadamardEJA(3) and JordanSpinEJA(3).
-
-7. Figure out if CombinatorialFreeModule's use of IndexedGenerators
- can be used to replace the matrix_basis().
-
-9. Add back the check_field=False and check_axioms=False parameters
- for the EJAs we've constructed ourselves.
+4. When we take a Cartesian product involving a trivial algebra, we
+ 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...
