Base.SexpableProvides functors for making modules sexpable when you want the sexp representation of one type to be the same as that for some other isomorphic type.

  (M : sig ... end) : 
  Sexplib0.Sexpable.S with type t := M.tmodule Of_sexpable1

  Sexplib0.Sexpable.S3 with type ('a, 'b, 'c) t := ('a, 'b, 'c) M.tmodule Of_stringable (M : Stringable.S) : sig ... endNew code should use the [@@deriving sexp] syntax directly. These module types (S, S1, S2, and S3) are exported for backwards compatibility only.
