(** This family of functions assumes its constr argument is known to be
well-typable. It does not type-check, just recompute the type
without any costly verifications. On non well-typable terms, it
either produces a wrong result or raise an anomaly. Use with care.
It doesn't handle predicative universes too. *)

disable "Prop-polymorphism", cf comment in [inductive.ml] *)
