Lemma tutu x y (A : 0 < x) (B : 10 < y) : True.
Proof.
pack hypothesis A.
(* Hypothesis A should have disappeared and a "packed_hyps" hypothesis
should have appeared, with unreadable content. *)
pack hypothesis B.
(* Hypothesis B should have disappeared *)
destruct packed_hyps as [unpacked_hyps].
(* Hypothesis unpacked_hyps should contain the previous contents of A and B. *)
exact I.
