Toplevel functions

The functions below are broadly useful when writing Async programs, and so are made available at the toplevel.

val catch : 
  ((unit -> unit) ->
    exn Async_kernel.Deferred.t)
    Monitor.with_optional_monitor_name

val choice : 
  'a Async_kernel.Deferred.t ->
  ('a -> 'b) ->
  'b Async_kernel.Deferred.Choice.t

val choose : 
  'a Async_kernel.Deferred.Choice.t list ->
  'a Async_kernel.Deferred.t

Infix operators and `Let_syntax` support

val (>>>) : 'a Async_kernel.Deferred.t -> ('a -> unit) -> unit

equivalent to Deferred.upon.

  ('a -> ('c, 'b) Async_kernel.Deferred.Result.t) ->

equivalent to Deferred.Result.bind.

val (>>|?) : 
  ('a, 'b) Async_kernel.Deferred.Result.t ->
  ('a -> 'c) ->
  ('c, 'b) Async_kernel.Deferred.Result.t

equivalent to Deferred.Result.map.

module Expect_test_config_or_error : sig ... end

An alternative to Async.Deferred_or_error_expect_test_config in which %expect has type unit rather than unit Deferred.Or_error.t. This lets one write:
