preserves the equality function

val add : 'a t -> 'a -> unit
val strict_add : 'a t -> 'a -> unit Or_error.t

strict_add t x returns Ok () if the x was not in t, or an Error if it was.

val strict_add_exn : 'a t -> 'a -> unit
val remove : 'a t -> 'a -> unit
val strict_remove : 'a t -> 'a -> unit Or_error.t

strict_remove t x returns Ok () if the x was in t, or an Error if it was not.

val filter : 'a t -> f:('a -> bool) -> 'a t
val filter_inplace : 'a t -> f:('a -> bool) -> unit
val inter : 'key t -> 'key t -> 'key t

inter t1 t2 computes the set intersection of t1 and t2. Runs in O(min(length t1, length t2)). Behavior is undefined if t1 and t2 don't have the same equality function.
