+(** This file extends ClassicalDescription.v with the axiom of choice.
+    As ClassicalDescription.v, it implies the double-negation of
+    excluded-middle in Set and implies a strongly classical
+    world. Especially it conflicts with impredicativity of Set, knowing
+    that true<>false in Set.

+Theorem choice :
+ forall (A B:Type) (R:A -> B -> Prop),
+   (forall x:A,  exists y : B, R x y) ->
+    exists f : A -> B, (forall x:A, R x (f x)).
+Proof.
