(* Bool *)
(** Provides a datatype for representing boolean formulas and evaluation,
iteration and map functions. *)
(** Public type for generic boolean formulas. An empty conjunction [And[]] is true and
an empty disjunction [Or[]] is false. *)
type 'a boolean =
And of 'a boolean list
| Or of 'a boolean list
| Not of 'a boolean
| Atom of 'a
| True
| False
val eval : ('a -> bool) -> 'a boolean -> bool
(** [eval g f] evaluates the boolean formula [f] using the values returned by [g] for the atoms. *)
val iter : ('a -> unit) -> 'a boolean -> unit
(** [iter g f] calls [g] over every atom of [f]. *)
val map : ('a -> 'b) -> 'a boolean -> 'b boolean
(** [map g f] replaces every atom of [f] by its image by [g]. *)
