(** The default expect test config in code which has [open Async].

    [%expect] has type [unit] rather than [unit Deferred.t].  This lets one write:

    {[
      [%expect {| |};
    ]}

    rather than:

    {[
      let%bind () = [%expect {| |}] in
    ]}

    It also means that [let%expect] cannot terminate with [%expect], and must instead
    terminate with [return ()]. *)
