proposition: Lemma weq_reindexing_forward_ob_eq_Split_eq {c' : C'} {x' y' : D' c'} : weq (x' = y') (Split_eq x' y').
proof: Proof. apply (make_weq reindexing_forward_ob_eq_to_Split_eq). apply (isweq_iso _ Split_eq_to_reindexing_forward_ob_eq). - exact (pr1 weq_reindexing_forward_ob_eq_Split_eq_opaque). - exact (pr2 weq_reindexing_forward_ob_eq_Split_eq_opaque). Defined.
