Functor Packed_array.Tuple2

module Tuple2: 
functor (A : Basic) ->
functor (B : Basic) -> sig .. end
the representation of a packed array of tuples is a tuple of packed arrays. This makes the zip_exn and unzip functions constant time.
Parameters:
A : Basic
B : Basic

type elt = A.elt * B.elt 
include Packed_array.S
val zip_exn : A.t -> B.t -> t
val unzip : t -> A.t * B.t
