proposition: Lemma whisker_right_id_2mor {C : prebicategory} {a b c : C} (f : a -1-> b) (g : b -1-> c) : whisker_right (identity f) g = identity (f ;1; g).
proof: Proof. intermediate_path (functor_on_morphisms (compose_functor a b c) (identity (make_catbinprod f g))). reflexivity. apply functor_id. Defined.
