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 +5. The main EJA element constructor is happy to convert between e.g. HadamardEJA(3) and JordanSpinEJA(3).
