(** 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. *)

(** The "polyprop" optional argument is used by the extraction to
    disable "Prop-polymorphism" *)

(** The "lax" optional argument provides a relaxed version of
    [get_type_of] that won't raise any anomaly but RetypeError instead *)

(** The "polyprop" optional argument above controls
    the "Prop-polymorphism". By default, it is allowed.
    But when "polyprop=false", the following exception is raised
    when a polymorphic singleton inductive type becomes Prop due to
    parameter instantiation. This is used by the Ocaml extraction,
    which cannot handle (yet?) Prop-polymorphism. *)
