Choice monad. See the Haskell library or this paper

See online documentation.

Example

> #require "choice";;
> open Choice.Infix;;
> let c = Choice.lift2 (fun x y -> x,y)
  (Choice.of_list [1;2;3;4]) (Choice.of_list ["1"; "3"]);;
val c : (int * string) Choice.t = <abstr>
> let c2 = Choice.filter c (fun (x,y) -> x = int_of_string y);;
val c2 : (int * string) Choice.t = <abstr>
> let c3 = Choice.take 2 c2;;
val c3 : (int * string) Choice.t = <abstr>
> Choice.run_n 4 c3;;
- : (int * string) list = [(3, "3"); (1, "1")]

Build status

Results of building choice with each compiler on check.ci.ocaml.org, run of against opam-repository 7cdc698. All results for this package.

Each result links to its build log. To keep crawlers from overloading the site, build logs require a GitHub sign-in (see ocurrent/opam-health-check). On your first log, GitHub asks you to “Authorize opam-health-check”, the OCurrent app that runs these checks; it sees only your public profile, not your repositories. The sign-in lasts 30 days.
