proposition: Lemma isaprop_disp_monoidal_laws {C : category} {D : disp_cat C} {M : monoidal C} (DM : disp_monoidal_data D M) : isaprop (disp_monoidal_laws DM).
proof: Proof. repeat (apply isapropdirprod) ; repeat (apply impred ; intro) ; repeat (try apply D) ; repeat (apply isaprop_is_disp_inverse). Qed.
