What’s New in F# 6 (devblogs.microsoft.com)

Really happy to see the task improvements. Simpler and more performant. Can’t beat that when improving interop with .NET.

I'm seriously loving F#. It's a steep learning curve from an OO background but it just feels more ergonomic to use.

look at this garbage syntax,

  let readFilesTask (path1, path2) =
     async {
          let! bytes1 = File.ReadAllBytesAsync(path1) |> Async.AwaitTask
          let! bytes2 = File.ReadAllBytesAsync(path2) |> Async.AwaitTask
          return Array.append bytes1 bytes2
     } |> Async.StartAsTask

async await.. so ugly. I have a heard time getting excited at this "state of the art" when parallel processing in Erlang is so ubiquitous and native.

  let readFilesTask (path1, path2) =
     task {
          let! bytes1 = File.ReadAllBytesAsync(path1)
          let! bytes2 = File.ReadAllBytesAsync(path2)
          return Array.append bytes1 bytes2
     }
