(* 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 [lsimpleconstr] 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. *)
