 5. Factor out the unit-norm basis (and operator symmetry) tests once
    all of the algebras pass.
 
-6. Create Element subclasses for the matrix EJAs, and then override
-   their characteristic_polynomial() method to create a new algebra
-   over the rationals (with a non-normalized basis). We can then
-   compute the charpoly quickly by passing the natural representation
-   of the given element into the new algebra and computing its charpoly
-   there. (Relies on the theory to ensure that the charpolys are equal.)

+6. Refactor the current ungodly fast charpoly hack (relies on the
+   theory to ensure that the charpolys are equal.)

+7. If we factor out a "matrix algebra" class, then it would make sense
+   to replace the custom embedding/unembedding functions with static
+   _real_embedding() and _real_unembedding() methods.
