-------------------------+-------------------------------------------------
The class `SymmetricFunctionAlgebra_generic` already has a
`coproduct_by_coercion` so the coproduct works after establishing a
coercion path. However, the product does not work without implementing
one of `product_on_basis`, `_multiply`, `_multiply_basis`,
`product_by_coercion` (the precedence order is established in
`categories.magmatic_algebras`).
By implementing `product_by_coercion` in
`SymmetricFunctionAlgebra_generic`, the product will be implemented once a
coercion path is established.
