+Parameter K : Type -> Type.

+Parameter bind : forall A B : Type, K A -> (A -> K B) -> K B.

+Parameter
+  bind_compat :
+    forall (A B : Type) (m1 m2 : K A) (f1 f2 : A -> K B),
+    equiv m1 m2 ->
+    (forall x : A, equiv (f1 x) (f2 x)) -> equiv (bind m1 f1) (bind m2 f2).

+Parameter
+  bind_val_l :

+Parameter
+  bind_val_r :

+Hint Resolve equiv_refl equiv_sym equiv_trans: monad.
+
+Add Parametric Relation A : (K A) (@equiv A)
+    reflexivity proved by (@equiv_refl A)
+    symmetry proved by (@equiv_sym A)
+    transitivity proved by (@equiv_trans A)
+      as equiv_rel.
+
+Add Parametric Morphism A B : (@bind A B)
+    with signature (@equiv A) ==> (pointwise_relation A (@equiv B)) ==> (@equiv B)
+      as bind_mor.
+Proof.
+  unfold pointwise_relation; intros; apply bind_compat; auto.
+Qed.
+
+Lemma test:
+  forall (A B: Type) (m1 m2 m3: K A) (f: A -> A -> K B),
+    (equiv m1 m2) -> (equiv m2 m3) ->
+    equiv (bind m1 (fun a => bind m2 (fun a' => f a a')))
+          (bind m2 (fun a => bind m3 (fun a' => f a a'))).
+Proof.
+  intros A B m1 m2 m3 f H1 H2.
+  setoid_rewrite H1. (* this works *)
+  setoid_rewrite H2.
+  reflexivity.
+Qed.
