(**** Tactics Tauto and Intuition ****)

(**** Tauto:
  Tactic for automating proof in Intuionnistic Propositional Calculus, based on
  the contraction-free LJT of Dickhoff ****)

(**** Intuition:
  Simplifications of goals, based on LJT calcul ****)

(* Fails because Tauto does not perform any Apply *)
Goal (forall A : Prop, A \/ ~ A) -> forall x y : nat, x = y \/ x <> y.
Proof.
   Fail tauto.
Abort.
