+(** The modular constr printer.
+    [modular_constr_pr pr s p t] prints the head of the term [t] and calls
+    [pr] on its subterms.
+    [s] is typically {!Pp.mt} and [p] is [lsimple] for "constr" printers and [ltop]
+    for "lconstr" printers (spiwack: we might need more specification here).
+    We can make a new modular constr printer by overriding certain branches,
+    for instance if we want to build a printer which prints "Prop" as "Omega"
+    instead we can proceed as follows:
+    let my_modular_constr_pr pr s p = function
+      | CSort (_,GProp Null) -> str "Omega"
+      | t -> modular_constr_pr pr s p t
+    Which has the same type. We can turn a modular printer into a printer by
+    taking its fixpoint. *)
