Sourceval eval_case_analysis : case_analysis -> EConstr.t * EConstr.types
Sourceval default_case_analysis_dependence : Environ.env -> Names.inductive -> bool

Build a dependent case elimination predicate unless type is in Prop or is a recursive record with primitive projections.

Sourceval build_case_analysis_scheme_default : Environ.env -> Evd.evar_map -> Constr.pinductive -> Sorts.family -> Evd.evar_map * case_analysis

Builds a recursive induction scheme (Peano-induction style) in the same sort family as the inductive family; it is dependent if not in Prop or a recursive record with primitive projections.

Builds mutual (recursive) induction schemes

Sourceval build_mutual_induction_scheme : Environ.env -> Evd.evar_map -> ?force_mutual:bool -> (Constr.pinductive * dep_flag * Sorts.family) list -> Evd.evar_map * Constr.constr list

Scheme combinators
