I wonder if the right way to do this is to create a lemma like @[simp] lemma asda : algebra.to_ring_hom = algebra_map R A := rfl and let simps do this; however, this lemma and simps {simp_rhs := tt} doesn't create the lemma we want yet

bors merge

I'm not convinced whether this simp-normal form is better or worse than the old one, but we can always remove simp at a later date if it becomes annoying.
