-5. Compute the scalar in the general natural_inner_product() for
- matrices, so no overrides are necessary. Actually, this is
- probably better implemented as a dimension_over_reals() method
- that returns 1, 2, or 4.

-6. The main EJA element constructor is happy to convert between
- e.g. HadamardEJA(3) and JordanSpinEJA(3).
+5. Profile the construction of "large" matrix algebras (like the
+ 15-dimensional QuaternionHermitianAlgebra(3)) to find out why
+ they're so slow.
