Module Retyping

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", cf comment in inductive.ml

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

type retype_error
exception RetypeError of retype_error
val get_type_of : ?polyprop:bool -> ?lax:bool -> Environ.env -> Evd.evar_map -> EConstr.constr -> EConstr.types
val get_type_of_constr : ?polyprop:bool -> ?lax:bool -> Environ.env -> ?uctx:UState.t -> Constr.t -> Constr.types

No-evar version of get_type_of

val get_sort_of : ?polyprop:bool -> Environ.env -> Evd.evar_map -> EConstr.types -> EConstr.ESorts.t
val get_sort_family_of : ?polyprop:bool -> Environ.env -> Evd.evar_map -> EConstr.types -> Sorts.family

Makes an unsafe judgment from a constr
