Plans for the future of OCaml's stdlib

One of the most common complaint about OCaml, from both newcomers and veterans, is that the stdlib is lacking in several domains. Among these we can list:

• some modules are absent but should exist (e.g. Option)
• some modules are present but lack some functionality (e.g. List could have many more combinators)
• the lack of some transverse features (iterators, printers, monadic operators…)
• the lack of generality of some constructs. Notably, in_channel

open Lwt.Infix

type order =

  | Flush

let write_order oc = function
  | String (s, i, j) ->
    Lwt_io.write_from_string_exactly oc s i j
  | Flush ->
