-6. Implement spectral projector decomposition for EJA operators
-   using jordan_form() or eigenmatrix_right(). I suppose we can
-   ignore the problem of base rings for now and just let it crash
-   if we're not using AA as our base field.
-
-7. Do we really need to orthonormalize the basis in a subalgebra?
-   So long as we can decompose the operator (which is invariant
-   under changes of basis), who cares?
-
-8. Ensure that we can construct all algebras over both AA and RR.
+5. Override inner_product(), _max_test_case_size(), et cetera in
+   DirectSumEJA.
 
-9. Check that our field is a subring of RLF.
+6. Switch to QQ in *all* algebras for _charpoly_coefficients().
