proposition: Lemma swap_along_zisos {C : category} {x1 x2 y1 y2 : C} (p1 : z_iso x1 y1) (p2 : z_iso x2 y2) : ∏ (f: C⟦x1,x2⟧) (g : C⟦y1,y2⟧), (pr1 p1) · g = f · (pr1 p2) -> (inv_from_z_iso p1) · f = g · (inv_from_z_iso p2) .
proof: Proof. intros f g p. apply z_iso_inv_on_right. rewrite assoc. apply z_iso_inv_on_left. apply p. Qed.
