proposition: Proposition internal_curry_uncurry (v₁ v₂ v₃ : V) : internal_curry v₁ v₂ v₃ · internal_uncurry v₁ v₂ v₃ = identity _.
proof: Proof. use internal_funext. intros w h. rewrite tensor_comp_r_id_r. rewrite !assoc'. unfold internal_uncurry. rewrite internal_beta. rewrite tensor_split. rewrite <- tensor_id_id. rewrite !assoc'. etrans. { apply maponpaths. rewrite !assoc. rewrite tensor_rassociator. rewrite !assoc'. apply maponpaths. rewrite !assoc. rewrite <- tensor_comp_id_r. unfold internal_curry. rewrite !internal_beta. apply idpath. } rewrite !assoc. apply maponpaths_2. rewrite !assoc'. rewrite mon_rassociator_lassociator. apply id_right.
