-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.
-
-8. Implement random_instance() for the main EJA class.
-
-9. Implement random_instance() for the subalgebra class.
+6. Add special det/trace method overrides for the algebras where we
+ know them? The only reason this might be tricky is because the
+ obvious solution is to subclass EJAElement, but then we might
+ collide with e.g. the Cartesian product element subclass.
