val of_list : (int * int) list -> t
val min_code : int
val max_code : int
val empty : t
val any : t
val union : t -> t -> t
val union_list : t list -> t
val difference : t -> t -> t
val intersection : t -> t -> t
val is_empty : t -> bool
val eof : t
val singleton : int -> t
val interval : int -> int -> t
