(** Check that [@Reflexive Prop ?r] picks the instance setoid_rewrite needs.
Really, we want to set [Hint Mode Reflexive] in a way that this fails, but
we cannot [1]. So at least we try to make sure the first solution found
is the right one, to not pay performance in the success case [2].

Lemma test_setoid_rewrite :
exists R, @Reflexive Prop R /\ R = iff.
Proof.
eexists. split.
- apply _.
- reflexivity.
