Ltac2 @ external get : ident list -> Std.reference option := "ltac2" "env_get".
(** Returns the global reference corresponding to the absolute name given as
    argument if it exists. *)

Ltac2 @ external expand : ident list -> Std.reference list := "ltac2" "env_expand".
(** Returns the list of all global references whose absolute name contains
    the argument list as a suffix. *)

Ltac2 @ external path : Std.reference -> ident list := "ltac2" "env_path".
(** Returns the absolute name of the given reference. Panics if the reference
    does not exist. *)

Ltac2 @ external instantiate : Std.reference -> constr := "ltac2" "env_instantiate".
(** Returns a fresh instance of the corresponding reference, in particular
    generating fresh universe variables and constraints when this reference is
    universe-polymorphic. *)
