proposition: Lemma monoidal_swapped_laws {V : category} (Mon_V : monoidal V) : monoidal_laws (monoidal_swapped_data Mon_V).
proof: Proof. repeat split. - intro ; intro ; apply (bifunctor_rightid Mon_V). - intro ; intro ; apply (bifunctor_leftid Mon_V). - intro ; intros ; apply (bifunctor_rightcomp Mon_V). - intro ; intros ; apply (bifunctor_leftcomp Mon_V). - intro ; intros ; apply (! bifunctor_equalwhiskers Mon_V _ _ _ _ _ _). - intro ; intros ; apply monoidal_rightunitornat. - apply monoidal_rightunitorisolaw. - apply monoidal_rightunitorisolaw. - intro ; intros ; apply monoidal_leftunitornat. - apply monoidal_leftunitorisolaw. - apply monoidal_leftunitorisolaw. - intro ; intros ; apply (! monoidal_associatorinvnatright Mon_V _ _ _ _ _). - intro ; intros ; apply (! monoidal_associatorinvnatleft Mon_V _ _ _ _ _). - intro ; intros ; apply (! monoidal_associatorinvnatleftright Mon_V _ _ _ _ _). - apply monoidal_associatorisolaw. - apply monoidal_associatorisolaw. - intro ; intros. cbn. rewrite (! monoidal_triangleidentity Mon_V _ _). rewrite assoc. rewrite (pr2 (monoidal_associatorisolaw Mon_V _ _ _)). apply id_left. - intro ; intros ; apply monoidal_pentagon_identity_inv.
