proposition: Lemma weq_reindexing_forward_Split_z_iso_ob_z_iso {x' y' : D' c'} : weq (Split_z_iso x' y') (z_iso_disp (identity_z_iso c') x' y').
proof: Proof. apply (make_weq Split_z_iso_to_reindexing_forward_ob_z_iso). apply (isweq_iso _ reindexing_forward_ob_z_iso_to_Split_z_iso). - exact (pr1 weq_reindexing_forward_Split_z_iso_ob_z_iso_opaque). - exact (pr2 weq_reindexing_forward_Split_z_iso_ob_z_iso_opaque). Defined.
