F# how to do List.map in parallel -


what lightweight, terse way run following code in parallel within standard f# libs? or failing used additional libs?

let newlist = oldlist |> list.map mycomplexfunction

the best find 

let newlist = oldlist |> list.map (fun x -> async { return mycomplexfunction x }                       |> async.parallel                        |> async.runsynchronously                       |> array.tolist

i don't because it's 4 lines long , constructs array have make list. if working arrays simple, array.parallel, want keep lovely immutable list functional purity. can't believe there no list alternative, far have been unable find one. suggestions?

use pseq module:

open microsoft.fsharp.collections  let newlist =      oldlist      |> pseq.map mycomplexfunction     |> pseq.tolist
