Variable A : Prop.
Variable B : Prop.
Axiom OR : A \/ B.
Lemma MyLemma2 : True.
proof.
per cases of (A \/ B) by OR.
suppose A.
then (1 = 1).
then H1 : thesis. (* 4 *)
thus thesis by H1. (* 2 *)
suppose B. (* 1 *) (* 3 *)
then (1 = 1).
then H2 : thesis.
thus thesis by H2.
end cases.
end proof.
Qed. (* 5 if you made it here, there is no regression *)
